so I've gotten 2 32 gig touches now from 2 different best buys in the last week and both have had the same problem. if I'm scrolling through music its the worst, but it also happens when I'm just browsing the web. It will just randomly return to the home screen, sometimes after only a few seconds. I've tried being extra careful of where i touch it, and it still returns. anyone else had this problem or know how to fix it?
