It works fine most of the time but when the rate of new events/messages gets too high ( unscientifically about 50 a second i think it can handle) it grinds to a halt and basically stops processing new events/messages and doesn't catch up even if the rate of new events/messages slows down. . I can't explain why it doesn't recover, but you would certainly expect this to be quite slow given Python is executing an infinite loop. Replacing the loop with just pythoncom.PumpMessages() also works, but I have no idea if this is more or less robust? That should be more robust and performant in your scenario. The only time you should use PumpWaitingMessages is when that infinite loop isn't what you want.

I'm using in my thread: while True: pythoncom.PumpWaitingMessages() There's a few stackexchange questions with vague answers, I'd really appreciate if someone could elaborate on some of these? https://stackoverflow.com/questions/28352419/python-win32com-pumpwaitingmessages-processing https://stackoverflow.com/questions/30691875/python-pythoncom-pumpmessages Replacing the loop with just pythoncom.PumpMessages() also works, but I have no idea if this is more or less robust? I've seen plenty of examples with some time.sleep in the while True loop, but that definitely doesnt work for my purposes. Happy to share more code if it is needed for context, but the application itself needs a paid subscription so it wouldn't be testable.
