Yeah, thanks for the tip. I've turned that setting to 100. It's a little hard to explain, but when it does "take" it flies. It's just that 2/3 times there's no response. If it was like this in all directions, I'd say I just need to get used to the thing. But it only happens when I'm moving upwards; every other direction is completely responsive. I'm starting to think I'll stop by AT&T tonight and ask if this is normal. It's pretty annoying--it's like a car that can't go in reverse, you know? Kind of a necessary feature.
