Here's a little annoyance from acrobat.
I'm running acrobat 8.1.1 professional, works great but no matter what. The first time I open a pdf and change focus to another app. The dock icon for acrobat bounces until I click on it. No changes, no updates nothing. It just decides to bounce.

I just felt like sharing. I know there's not much I can do about it.
