You can have one thread raise an exception in an other thread. Read my answer in the "thread and alarm" thread. > for implementing something like an > "abort" button?

Some questions. 1) Did you call gtk.gdk.threads_init() ? 2) Did you call gtk or gtk.gdk calls from an other thread? 3) Are you on windows of linux? Some introductiory text about using threads with gtk is on http://www.pardon-sleeuwaegen.be/antoon/python/page0.html However a lot is linux specific. There is also a mainling list for pygtk users.
