allegro 4.1.16
my allegro app crashes in 16bit mode, running on a 16bit desktop.
when i alt-tab away from the fullscreen driver it crashes.
it does not crash in the debug mode.
only the release version.
i also tried 32bit desktop and it does NOT crash.
here is the only info i could find.. the crash location is marked with an
arrow.
