Calling Freeze/Thaw for every message slows it down too much, try this
instead:


        if used or (not self.hideUnused.GetValue()):
            while self.msgHistory.GetLastPosition() > 29000:
                self.msgHistory.Freeze()
                # delete first line of history
                #print self.msgHistory.GetLineLength(0),
self.msgHistory.XYToPosition(0, 1)
                self.msgHistory.Remove(0, self.msgHistory.XYToPosition(0,
1))
                self.msgHistory.Thaw()

            self.msgHistory.AppendText(eventText)
            #print self.msgHistory.GetLastPosition()

This way they're only called when deleting from the list.  BTW, yes this
seems to fix it.
