--- Comment #2 from Jacek Caban jacek@codeweavers.com --- Yes, NtUserDispatchMessage is currently broken. As a hack, we could use a similar to track_menu() or move exception handling to PE side, but we need some more improvements for exception handling in client callbacks anyway. I'm working on it, but it's not ready yet.
