Reply to S2 audio drops on windows 7 during browsing/loading only? Help?

As topic states I'm only getting drops when I scroll though tracks and/or load into decks.

I can have all 4 decks playing w/ FX and only at 60% CPU and 1.6gb of 4gb memory usage.

Transferred all files from external drive to hard drive of machine believeing that might be the problem to no avail.

I run the performance script posted a few months ago in the DJTT blog to shut down services, and again my performance numbers above seem legit.

Anyone have any ideas? Is this when peeps normally experience audio drop outs?
