Presets constantly change superfast

[Squirrelmaster]

I installed Milkdrop on my WIndows XP P4 comp w/ TNT2 32 meg card. It worked fine for a week, but now I have a huge problem. The presets constantly change at superspeed, as in 5+ presets per second! This means it never stays the same and just looks like garbled lines, which greatly interferes with me enjoying the program! I looked through the Docs and found nothing. The defaults are restored on the config menu, and I would mess with the config file (the notepad file in milkdrop folder) except I cant find docs as to what each config stands for. HELP!!
