Pro Tools 10: Insanely slow? (Video included)

[Soundburst]

Hey everyone,

I'm trying to do some work on my new MBP. (13inch, i5, 2.4GHz, 4GB Ram, Lion 10.7.2, Pro Tools 10 + 9.0.6) and even when I just create one track. . .if I go to automation and try to drag the volume level it's slow and laggy. Like. .as opposed to before where I'd click it, a dot would appear, and I could instantly drag the level desired - now I have to wait a second or two before it does anything.


I uninstalled Pro Tools 10, and installed Pro Tools 9 and it's the same.

Here's a video of the problem - EVERYTHING has this level of lag. In this clip I click and drag across the sound file and you see how long it takes to respond (watch in HD to follow the mouse icon's movement):
