Before processing the next key event, lock again. By locking that spin lock, a thread can catch the main thread sleeping, and keep it sleeping until whatever non-threadsafe has been done. The user thread will not become main thread, but at least the main thread will not interfere. However, this doesn't solve the popup problems, eg. a simple way to activate a cOsdObject without abuse of MainMenuAction. Cheers, Udo
