Is everyone sure that Win95 doesn't like Allegro's timers? I tried the 
triple-buffering example program (with the triangles) under Win95. It 
gives a warning at the start ('Windows detected, this program probably 
won't run but press a key to run it anyway' or something) but I couldn't 
see any difference between running it under Win95 and anything else (DOS, 
3.1).

Could it be a newer, nicer version of Win95? (I don't know - I'm just 
guessing, but the computer was quite new.)
