Hi,

I've noticed that whenever I switch out of an Allegro app using theCTRL-ALT-DEL combination and then press the task-manager button, myallegro app continues to run in the background (the app's cpu-usage is99% and when I switch back in, the app looks like it's been runningcontinuously). However, when I switch out using ALT-TAB, the app freezesand uses up 0% cpu and returns to normal when I switch back in.

I am using the MSVC build of Allegro 4.2.1 under Windows 2000. I do notcall set_display_switch_mode() anywhere in my program.

AE.
