Unless the GUI thread has a chance to take passes through the wxPython mainloop, the progress bar, etc., may not actually be updated on some platforms. Mr. Sherman would likely be better off creating a new thread which handles processing, which could update a C global variable, which the GUI thread can poll to update its progress bar, etc. Alternatively, if the processing can be broken down into smaller pieces, the secondary thread can call the pieces and post events back to the GUI thread to update the progress bar (via explicit wx.PostEvent or implicit wx.CallAfter). - Josiah -- http://mail.python.org/mailman/listinfo/python-list
