I've been running WordPress for quite some time, and have recently upgraded to 2.0.2. Everything was working perfectly until I switched to a new theme (Unionjack) and modified the CSS a bit to match the colors/background/header graphic that I chose.
Now it's doing a weird thing: randomly, about once or twice a day, it switches back to the default theme all by itself. It will do this even if I'm not logged in.
Is there any WordPress function that might be being called by the theme to do this? I can't figure it out...

Any help would be appreciated. Thanks!
