an hour or so, and you have to kill it and restart it. That's a new one. Any other symptoms? Can you get a backtrace from a coredump?

The good news is I could not reproduce it. But when it happens again I'll know who to notify.

As I recall, the problem would occur in the query analyzer. If there was highlighted text in the top window, and you highlighted a row in the results, and then clicked into the upper window while dragging the mouse, it would freeze the X server. It has happened much much less often lately, but it did happen just two days ago, and it always involves a click-drag situation.

Yes, that seems a gtk issue. You mark, then klick accidentaly into
the marked text (usually to change the mark area) and in the result
you are dragging the text to nowhere. pgadmin and X freezes in this
case. However you can login via another box and just kill pgadmin
to unfreeze. Maybe there is a problem with how drag & drop
is/isnt handled by the code? I have no idea.
It only happens in pgAdmin III, though, so it must be some strange interaction between wxWindows and GTK. I believe that the window manager
is part of the problem too, because I've used KDE (together with kwin)
for the last few years, and while it had this freezing-problem initially, it went away with some update. I believed that a wx or pgadmin update solved this, but now I'm using Gnome (together with metacity), and the problem is back... :-(

However, I figured out that if you press ALT-<key> with <key> being the
shortcut for some menu _directly_ after the freeze, the menu opens, and
the mouse pointer is restored back to it's normal shape... It won't work
if you click around after X freezes - I guess pgadminIII has to still have the focus for this to work...
