lockups in win32

[Greg Steffensen <greg steffensen gmail com>]

Hey, I'm developing an app in for windows using python and PyGTK, and
it sometimes locks up, and the locks up the entire windows xp
interfrace.  I'm pretty certain that the main bug is in my code,
not GTK, but I'm trying to figure out what could cause the entire xp
interface to lock up.   Specifically the app freezes, and
then you can click around xp for a bit, but it quickly freezes too (for
some reason, trying to access the find entry on the start menu always
makes it freeze instantly).  What does this signify?  Is an
error in the gtk main loop supposed to be able to cause this, or this a
bug in gtk/pygtk in addition to my own bugs?
