I've notice when I'm in the editor, the Flash Player can get excruciatingly laggy, enough to make Firefox crash. But when I back out of it and just look at it in the viewer, it works perfectly smoothly. Why does this happen, and will it get fixed?

I'm noticing this same behavior on one of my slower computers. It is running Chrome on XP. Looking at scripts is fine. But, trying to drag them around the screen causes Chrome to become unresponsive.
