Issue: Snow patches changing on their own

[x0x]

I'm having an issue with my Snow and Live 8 where something randomly changes the patch data on the Snow.

For instance, I'll set Bank 1 to use RAM1 4-5, and lets say that patch is named MorphingPad1.

Occasionally when I hit play, something changes that patch to a completely different patch, like Lead1. What is interesting is that it will still show that it is using RAM1 4-5, but with a different patch name. If I change it to RAM1 4-4 and then back to RAM1 4-5, it will momentarily display and play the correct patch (MorphingPad1), but will revert to the other patch (Lead1). I have to reboot to get the correct patch to load. I usually get about an hour out of live before this starts to happen. I reboot, get another hour.

I'm not sure if this is the Snow or Live 8, but something remembers the patches on the snow when I load my Live set. Does anyone know how to turn that off, or what might be causing this issue?
