Communication OS thread -> wx has to be done in a certain way. You must not do this directly, i.e. you must not call wx code from w/i an OS thread. See the wxPython Demo for an example of what you want to do: Process and Events -> Threads. Cheers Thin -- http://mail.python.org/mailman/listinfo/python-list
