\layout Title

Known BUGS in LyX
\layout Date

Last updated 1999-01-26
\layout Standard

This file contains a compilation of bug reports that have been sent to the
mailing list
\family sans
[email protected]
\family default
.
We try to keep it up to date as far as possible, but of course it's better
to spend time fixing bugs instead of archiving them.
Since we cannot reproduce all of these bugs, please send us any details
and updates and, of course, fixes.
\layout Section

How do I submit a bug report?
\layout Standard

All bug reports should always include information about which versions of
LyX the bug appears in (you will be surprised to know how many forget that
information).
Try to get the latest version of LyX and see if the problem still exist
before complaining
\begin_float footnote
\layout Standard

This is especially important if January 1999 is more than a few weeks ago,
in which case chances are that a newer development version of LyX has the
bug fixed.
\end_float
.
New releases will typically contain bug fixes :-)
\layout Standard

Remember: the less time the developers have to spend to understand and fix
a problem, the faster the problem is likely to be fixed.
\layout Standard

Other than that, the good bug report is characterized by including
\emph on
all
\emph default
relevant information and only that.
It's always relevant what the problem is, and how the problem is triggered.
If it's a compilation problem, include
\family typewriter
\size small
config.log
\family default
\size default
and information about your system (
\family typewriter
\size small
uname -a
\family default
\size default
), which compiler you use, versions of libraries and so on.
\layout Standard

If you found a bug that causes LyX to crash, please take the time to produce
a backtrace with a non-stripped lyx executable.
The one built in the source directory is per default not stripped, while
the installed binary is stripped.
So, run LyX from gdb by typing
\begin_inset Quotes eld
\end_inset

\family typewriter
\size small
gdb /users/bozo/lyx-1.0.x/src/lyx
\family default
\size default

\begin_inset Quotes erd
\end_inset

and then
\begin_inset Quotes eld
\end_inset

\family typewriter
\size small
run
\family default
\size default

\begin_inset Quotes erd
\end_inset

.
Make LyX crash and you'll return to gdb.
Use
\begin_inset Quotes eld
\end_inset

\family typewriter
\size small
bt
\family default
\size default

\begin_inset Quotes erd
\end_inset

to produce a backtrace and include the output in the bug report
\begin_float footnote
\layout Standard

if you want to be thorough, use the
\latex no_latex

\begin_inset Quotes eld
\end_inset

info locals
\begin_inset Quotes erd
\end_inset

and
\begin_inset Quotes eld
\end_inset

up
\begin_inset Quotes erd
\end_inset

commands to print out the values of local variables at a few stack levels.
\end_float
.
If possible, then a description of a way to reproduce the bug is more important
than a backtrace, because then we have the possibility to roll our own
backtrace.
If the bug is not easily reproducible, a backtrace is essential, because
then that might be all we've got.
\layout Standard

Bug reports should be mailed to the developer's list at
\family sans
[email protected]
\family default
.
However to avoid that we get cluttered with the same bug reports from many
people, we recommend that you either check the archive of the developer's
mailing list at
\family typewriter
http://www.mail-archive.com/[email protected]/
\family default
or subscribe to the list first.
If you want to be a real sport, you provide a patch along with the bug
report.
\layout Section

Bugs
\layout Enumerate

The LyX keyboard mappings, including dead-keys, do not work in pop-up dialogs.
You can try cut & paste from a text editor.
\layout Enumerate

It is not possible to enter
\backslash
dj{} or
\backslash
DJ{} as LaTeX accent insets; this means that these characters are not available
to people who want to use latin1 as encoding.
\layout Enumerate

On a very small (
\begin_inset Formula \( 640\times 480 \)
\end_inset

?) screen, math panel pops up the subpanels off screen.
It should check it's position, and put the panels somewhere visible.
\layout Enumerate

\family sans
Options->Keyboard
\family default
has no Apply and Cancel buttons.
[
\emph on
Note from Asger: Well, I think the entire form should be redesigned, such
that it isn't dynamic.
Also, it should not be possible to select a non-existing keyboard mapping.
In other words, the drop-down list should show exactly those that are available.
Similarly, the charset definition should be a droplist too.

\emph default
]
\layout Enumerate

The vertical scroll bar of the preamble window is broken.
If you resize the window, strange things can happen, including a fatal
crash! This is a bug in XForms.
\layout Enumerate

The
\family sans
Layout->Character
\family default
pop-up toggles rather than sets attributes.
Use
\family sans
Reset
\family default
first, and then set the attributes to get a real set.
[
\emph on
Update: work has been done to improve this situation.
Feedback welcome
\emph default
]
\layout Enumerate

The
\family sans
Citation Reference
\family default
command doesn't escape
\begin_inset Quotes eld
\end_inset

\family typewriter
_
\family default

\begin_inset Quotes erd
\end_inset

characters in the remarks field when generating TeX documents.
You have to type
\begin_inset Quotes eld
\end_inset

\family typewriter

\backslash
_
\family default

\begin_inset Quotes erd
\end_inset

by hand in these remarks if you want to use an underscore.
Similar for other special characters.
\layout Enumerate

If a figure is larger than one page down press would have taken you, the
page down fails and you are left where you started.
[
\emph on
Comment: behavior in this situation is improved but still imperfect.
LyX now does the pageup or pagedown, but jumps from the top to the bottom
of the figure, potentially skipping part of the middle.]
\layout Enumerate

If you delete marked text, the text is not deleted, but
\begin_inset Quotes eld
\end_inset

cut
\begin_inset Quotes erd
\end_inset

, which deletes the current text in the clipboard.
\layout Enumerate

Sometimes, when you delete large sections of text, the screen will appear
empty, and you have to use the scrollbar to make the cursor visible again.
\layout Enumerate

You can not export a selection from LyX to another X11 program.
Not even between two instances of LyX.
You can only paste into LyX using the middle mouse button.

\layout Enumerate

If you have edited and then undo all changes, then the
\begin_inset Quotes eld
\end_inset

Changed
\begin_inset Quotes erd
\end_inset

status is not reset.
\layout Enumerate

If you have a margin note in itemize text and the first paragraph of the
margin note is also itemize text it is possible to
\begin_inset Quotes eld
\end_inset

depth-increment
\begin_inset Quotes erd
\end_inset

and make the first itemize paragraph in the margin note deeper on-screen
even though LaTeX doesn't permit this (and ignores this).

\layout Enumerate

A table which is larger than the screen manages to go outside the red lines
drawn by a table float.
Same goes for figures.
A similar thing can happen with large mathematical equations.
Resize your LyX window.
\layout Enumerate

It is not possible to include footnotes in tables.

\layout Enumerate

The math editor does not support the optional argument of
\family typewriter

\backslash
sqrt
\family default
.
A workaround is to add
\begin_deeper
\layout LyX-Code

\backslash
newcommand{
\backslash
nthroot}[2]{
\backslash
sqrt[#1]{#2}}
\layout Standard

to your LaTeX preamble and use directly this function in your math formulas.
\end_deeper
\layout Enumerate

When going into math text mode (which results in
\family typewriter

\backslash
mathrm{}
\family default
in the LaTeX output) it is impossible to enter punctuation, as this is
always put back into math mode.
\layout Enumerate

If a LaTeX command is partially bold, it doesn't generate correct LaTeX
commands.
LaTeX commands written using the LaTeX layout or the LaTeX font state should
always use the standard font (this means no font changing commands should
be allowed).
Don't use font changing commands when you are in LaTeX mode.
\layout Enumerate

If you change font in a special word (like in
\begin_inset Quotes eld
\end_inset

\bar under
L
\bar default
aTeX
\begin_inset Quotes erd
\end_inset

), the whole word will have the font of the first character in dvi output.
This can be solved by using for example
\begin_inset Quotes eld
\end_inset

\bar under
L
\bar default
\latex latex
{}
\latex default
aTeX
\begin_inset Quotes erd
\end_inset

, thus disabling the automatic translation to the macro
\family typewriter

\backslash
LaTeX
\family default
.
\layout Enumerate

In a LyXCode environment, you can't have an empty line.
You'll have to type a single space to make it work.
\layout Enumerate

It is possible to use the subfigure style to get two small figures (side-by-side
), each with a caption and label, and then a common caption and label for
the entire figure.
LyX currently seems to support this in the pop-up menu for an eps figure.
However, I am unable to successfully add labels to each of the subfigures.
If I insert a label next to each subfigure, the labels appear fine and
can be cross-referenced in the usual manner.
However, the actual output (dvi or ps) does not distinguish between the
two labels and any cross-reference gets the same number.
You have to use plain old raw LaTeX mode and do this by hand.
\layout Enumerate

If you close a document while some included images are still in the rendering
phase, all images in newly opened documents will stay in the rendering
phase, making it impossible to preview or print the document.
You can't fix this by killing gs-processes, because there aren't any.
You'll have to restart LyX to work with figures again.
\layout Enumerate

If you preview an empty document, no dvi-file will be created, and xdvi
will not start.
We should present a kind warning to the user rather than be silent.
\layout Enumerate

Document that includes others: if LaTeX reports an error during the execution
of LaTeX on a sub-document as a chain reaction of executing LaTeX on a
higher level document, LyX places the error window on the correct position
of the higher level doc, not of the lower one.
There might be some spurious document corruption effects related to this.
Be careful with raw LaTeX in sub-documents.
