How to reproduce: put the following lisp code in a file and load it at startup, say xemacs -vanilla -l /tmp/tmp.el What i get at the first glance looks as expected: awful underlined italic in red on black (huh), but the buffers tab is unstable!. What do i mean -- any key press in XEmacs, some unreproducible mouse clicks outside(!) XEmacs cause tabs to disappear. The following behavior is unpredictable -- they might appear, then disappear again, and so on. Here are two screen shots -- the first is just after startup, the second -- after inserting the phrase "Where are the gutters?". The tabs disappeared just after pressing W. Moreover, the first screenshot is a kind of trick -- i had to start gimp, then invoke screenshot, using alt-tab switch to terminal, start xemacs and then "shoot" it. The complication is that clicking somewhere outside XEmacs caused tabs to hide, so i had to prepare screenshot in advance and only then invoke xemacs. ------------------------------------------------------------------------------- uname -a: Linux hookah 2.2.12-20 #5 Thu Feb 3 17:25:10 MSK 2000 i686 unknown ./configure '--with-sound=none' '--with-pop' '--error-checking=none' XEmacs 21.2-b31 "Iris" configured for `i686-pc-linux'.

What do you think about attaching menues to tabs on button3? Something like Switch To Buffer Switch To Buffer, Other Frame Save Buffer Save As ... Kill Buffer Anyway, great work. Nick.
