Hey folks, I recently got a new 30gb ipod and I'm finding the wheel to be super-sensitive. When I'm about to select a song it can (not always) jump to the one above or below it. I don't have this problem with my nano but I'm thinking maybe it's because the nano's wheel is smaller? Do any of you guys find that it's prone to *jumping* also? I have the box to send it back but there's no point if this is how they all behave. A friend told me that any moisture on your fingers can make it more sensitive. Any truth to that? Thanks.
