I used PPT 2010 in Beta and found an issue which your developers found a fix for, but I was told it involved "setting a reg-key", and that I should contact Microsoft after release to get instructions. The problem still persists in the released version. I've posted the question in the animation section to no avail. The PPT blog directed me here, so maybe this is where the really really smart people hang out?
The problem is hesitation on slow, repetitive animations.
Here is a link to a sample file that demonstrates the behavior:

Details are noted in the comment on the slide.
Help with this greatly appreciated.
