I'm gonna write some things I'd do in your case, hoping to help you to
find out what the problem is.

I would:

1. Run xwininfo against the window that eventually disappears to get its
   window ID.

2. Wait for it to disappear.

3. When it disappears, run sawfish-client and try to find some
   information about it (check the X log file, e.g. .xsession-errors, to
   see if there is something strange there.)

4. Try to bring the window back to the screen if it still exists. :-)

#<window 1200003>

PS: 0x1200003 (the window ID) is one of the information xwininfo can
give you.

If you get a window as the return value of `get-window-by-id', you can
try some functions to see if you make it appear again (e.g.,
uniconify-window, raise-window, set-input-focus, unshade-window)

If you don't get a window and the process is still running, well... So
there's a bug somewhere. :-)
