Ok, here's bug #2 that I've found on the iPod Touch.
One of the features the iPod Touch has is to automatically shut off the screen after a couple minutes to save power. When it does this, it locks the controls in the screen. In order to bring the controls back, one of the things you can do is double click the home button. This turns the screen back on, still locked, but displays controls on the screen that you can use to pause/continue, fast forward, rewind, and adjust the volume. The problem is, with these controls that come up on the locked screen, it seems like it's very hard to aim right and press those buttons so they respond. The buttons seem to work fine when it's unlocked. It's just these locked buttons that seem to not respond well.
Maybe I'm just imagining it, but they don't seem to respond right.
