AE has developed a strange zoom behavior. If I center up the comp, I hit the period key and it zooms off to the left. I hit the comma key and it reduces back to the right. A second press of either key zooms or reduces the comp to the same direction. I've tried scroll wheel and period/comma keys and I get the same behavior.
No idea how it started but it's been going on since yesterday. It's driving me crazy having to grab the comp with the hand tool and drag it back into center.
Any ideas how this can be corrected? I've tried a Help Search and web search but found nothing useful.
