I can confirm this bug. For now I have worked around it by explicitly telling unclutter to disable itself over TeXmacs windows: unclutter -notclass TeXmacs

When I reproduce this issue, it is NOT a crash -- it seems that when unclutter restores the mouse pointer, it also sends some event to TeXmacs which has the same effect as C-x C-c; TeXmacs tries to quit. If you have unmodified changes, then it will prompt you before quitting. Before I realized that the problem was caused by unclutter, I always made it a habit to modify my documents immediately after saving, so that TeXmacs wouldn't quit when I moved the mouse.

Vladimir G. Ivanovic reports:

I get the same startup behavior without unclutter but with a GNOME Terminal or a Multi-GNOME Terminal because they hide the mouse automatically when entering their window. TeXmacs will exit with or without unclutter, but only when the TeXmacs window overlays the terminal window.

After your announcement on freshmeat.net yesterday I was curious to try out TeXmacs-1.0.1.23. Compiling and installing went fine, but when using the program, it crashes (or more accurate it silently disappears ) very often for no obvious reason.

But I can't find a reason for this, so I compiled it with different optimizations, installing newer version of tetex and guile always with the same result.

So, to make a long story short I found the problem. It is me using a program named "unclutter", which hides the mouse after some idle time. I need a few hours to realize this :-)

When you move the mouse from the root window in the program window and open for example the help menu and move the mouse back to the root of the desktop nothing happens. But when you move the mouse in the program window and leave it there, than after some idle time the mouse hides itself, only then TeXmacs crashes when you move the mouse and it becomes visible again.

Some specs:
gcc 2.95.3
XFree86 4.2.0
Window Maker 0.80.2

and http://www.x.org/contrib/utilities/unclutter-8.tar.Z in case you want to try it yourself :-)
(I use unclutter -idle 2)

Simple solution:

Turning of unclutter and everything works without any problems :-)
