If I recall, the more watch windows and the more registers you are watching, the slower it will run. Shut down all but the essential registers you're looking at and it should run faster.

I looked at the CPU usage, and during a run MPLAB is using an average of about 1%, with the remainder spent in idle. Is this supposed to happen?
