debug window dissapears!

I tried my game on 2 different PC's one with Win98 and one with WinXP and when there is an error in the game, the debug window appears and dissapears before I can even look at it.

does anyone know if there is anything I can do to make it stay?

What do you mean by "debug window"?

I recon he means the alert window that pops up and tells about any errors etc - ie. "Memory Access Violation"

the debug console that you use to look at the variables

EDIT- oops my bad,it was an END statement I had forgotten about
