I've been using Window Maker, versions 0.20.something all the
way to 0.50.3. I always use focus-follows-mouse, but have
never seen this bug. Perhaps it's a locale/keyboard and gdk/gtk
thing (where gtk is putting focus on a widget (the combo) where
it's waiting for keyboard input). This is really weird. I've
built AbiWord on 5 different architectures, on 8 different Unix
operating systems, over 3 versions of X11, and have never seen
this bug. :)
If you really want to help find this, build a debug version of
AbiWord, start up gdb on it, set a breakpoint on
"gtk_combo_popup_list" (the gtk function called whenever the
list is ready to show itself in pop-down mode). Then do a
backtrace ("bt") and mail that to me so I can see if it's us
prompting a popdown somehow, or gtk.
You'll probably need a hand-built debug version of the gtk
libraries for this (so it can find its source code for source-level
debugging).
I actually have a suspicion it might be us doing something wrong,
but I'm surprised I've never seen this problem before.
