Hi,
I've been using LyX for quite a while, on a variety of machines. It's really
nice work! Thanks very much. One setup I use (rather frequently,
unfortunately) is to run LyX on a remote machine running Linux, log in from
a Windows machine via ssh, and use Reflection 7 as X server. This works well
*except* that certain key combinations in math mode cause LyX to crash.
(These seem to involve characters TeX reserves, for example putting any of
{$, %, #, @} in a sub- or super-script will cause a crash). Also, selecting
"Bibliography" has the same effect.
This problem *doesn't* happen when I display on the remote machine's
display, nor does it happen on my laptop.
The problem has survived through several Linux distriibutions (Mandrake 8.0,
Red Hat 7.1, Slackware 8.0) and all LyX versions I've tried
(1.1.6fix1-1.1.6fix4, built from source or rpm, both XForms versions).
When I run gdb I see LyX receiving an X error (line #6 below). This
backtrace comes from starting LyX under gdb, selecting File->New,
Insert->DIsplay Formula, ^$. Has anyone seen this behavior? Can anyone help?
Thanks
