While loop not working?

racefreak (18)
I have a while loop in my program, but it's not working properly. It will take a long time to finish a relatively short 'if' sequence. The strangest thing is, if you click anywhere outside the program, it completes instantly, whereas it take a long time when you're in the program itself. Any solutions?

Please post the code.

So that's basically what it looks like. Any suggestions? I'm totally stumped here.

Any suggestions?

Thou I am not completely sure of your problem, for I never used Allegro, I can strongly assume it is caused by abusing release_screen(); and destroy_bitmap (Image); over and over very very fast. See, when you press 'r', what you doing is probably causing the system to slow down by having to constantly update in a very short period of time. I suggest you create a separate draw function and also have the game speed capped (with a timer).

OK, I changed it so that it only uses acquire and releas screen twice, but I'm still having the same problem. And remember that when I click outside the program, it runs through it instantly. I just can't figure it out!
