I'm having this weird, intermittent bug. When I take my finger off my Apple Magic Trackpad and then, put it back down and move to the right, it takes a split second to respond. But I normally move very quickly so it's very disorienting. The weird thing is, it only happens when I move to the right, or in a diagonal direction that includes right. Up, down and left haven't shown any lag yet. It keeps starting and stopping. Most of the time it works as good as ever. But it seems like every few minutes this bug starts up again and then goes away. But, it's not crippling. I'll just have to be aware, and get used to it, for now.
