--- Comment #4 from Alexandre Julliard julliard@winehq.org 2010-08-19 06:01:55 --- Looks like a bunch of window timers are still running, and the app is trying to delete invalid ones. Maybe some confusion with timer ids. I'd suggest to first try a message spy under Windows to check if it also happens there.
