might be a character you downloaded or you did you download the patch

Happens since i have Vista, however only in cases where at xp mugen would have crashed without error. Guess it happens sometimes when i skip the loading process.

Most Of The Time It Happens If You Play To Hard And 1337 Or If You Hit Esc Allot.

It happens when you have a ton of things in your mugen that take up memory. It also happens when you leave your mugen on for too long.
