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...
