In the case above, it is a RedHat ghostscript bug.

That's odd. How do you navigate ? Using the menus is the killer problem
with xforms.

what happens is that the completion message from ghostscript is dropped by
xforms before we can see it, so we think that ghostscript is still rendering.
This was a much more serious problem until :
2000-12-04 John Levon <[EMAIL PROTECTED]>
* src/spellchecker.C: fix figures with pspell enabled
* src/insets/figinset.C: workaround for gs hang xforms bug
which introduced the fl_set_preemptive call. This lets us get many more of
the ClientMessage events. But xforms still drops them w/o telling us in some
circumstances involve fl popups, for example menus.
We can't do anything about that until a new xforms version is released (i.e.
never).
if you have any further questions, don't hesitate ...
