    AE CS6 painfully slow when active window, fast when inactive


      I'm having a problem that's absolutely driving me nuts right now (and this happened with CS5.5 as well, so it's not just CS6):


      AfterEffects sometimes gets painfully slow to work in... after moving the timeslider in the timeline (or in a footage window) to a specific frame it takes ages to show that frame. BUT: As soon as I switch to another program (or to my desktop, or just by clicking Windows' task bar - basically anything that takes the "focus" off of AfterEffects), AE speeds up like crazy. And it happens with rendering too: I get like 1 frame every 10 seconds when rendering an image sequence, but as soon as I make AE an inactive window, it speeds up to like 10 frames per second. What's going on? What might be causing this?


      I'm running a Core i7 950 @ 3.07GHz with 24GB of RAM and a GeForce GTX 480 on a dual monitor setup.
