Ok, so you know how when you hold down, it'll switch between the visual and whatever info you have up? I've been having trouble lately swtching between the two. I'll hold the down button, and it won't do anything. So i have to keep doing it, sometimes up to 3 or 4 times. As you can imagine, it can get annoying. Does anyone else have this problem? The button doesn't seem broken or anything either.
