--- Comment #6 from Henri Verbeet hverbeet@gmail.com 2009-12-20 13:47:26 --- It's probably much more interesting to look at what messages are actually filtered by changing the relevant TRACE in swapchain_process_message() to a FIXME or something. You're probably looking for something like WM_ACTIVATE (0x6) or WM_SETFOCUS (0x7).
