Basically, my MBP seems to 'lag' very bad where there's some type of data transfer going on. Downloading files or transferring files to another computer always replicates the problem.

This only happens when I have my MBP connected to my 27" monitor in a 'clamshell'. The whole OS feels like a slide show. The mouse crawls across the screen when moved. The keyboard takes a bit to catch up to my typing.

I've search google a bit, but can't seem to find anyone with a similar problem. Any suggestions?

Mid 09 base model 13" MBP.
