Black screen for 5 seconds when using the scroll wheel

I bought a Sansa Fuze from, and was excited to use it. But I noticed there is a nasty bug. Every time I use the scroll wheel, the screen goes blank for five or so seconds, then the screen is restored. I have charged it up to full battery but it didn’t fix it. I also formatted it, but this also did nothing. I can’t use it like this…

Return it?

There’s not much more you can do…  This isn’t a common occurance and should not happen so there’s obviously something wrong with your Fuze.
Since you’re arleady tried formatting it and reinstalling the firmware I really don’t know what else you could do.
