--- Comment #25 from Dmitry Timoshkov dmitry@codeweavers.com 2008-04-20 23:29:36 --- Probably calling ChangeDisplaySettingsExW(NULL, NULL, NULL, 0, NULL); on DLL_PROCESS_DETACH in user32 would do the trick, but it's not clear if that's the right thing to do, especially if an exiting process is not the one who has changed the resolution, or the resolution has been changed on behalf of other process.
