I recently upgraded from my 10GB scroll to a 30GB touchwheel, which I love... but I have this occasional problem.

Once in a while in shuffle songs mode (usually while playing one of my own playlists), the pod will start (for lack of a better term) freaking out. First thing I notice is that tracks start skipping; when I look at the unit, I see that it's behaving like I'm going crazy with the scroll and menu button, back and forth, up and down, skipping songs and playing other lists at random. I can hear and feel the drive humming conspicuously when this happens. Eventually, I just have to try and get the thing to shut down or reset to make it stop.

There doesn't seem to be a pattern as to when this occurs, as far as I can tell. Previously, I just figured that maybe I did something to the scoll by accident without locking the unit before putting it in my pocket or in the case, but just now it did it while innocently sitting on top of my desk. This has happened maybe 3 times in the 4 weeks I've had it.

Anyone else had this problem?
