Computer bogged down by PT and/or PAHUD

[thing85]

Fairly recently, my computer has been slowing down when I play 6+ tables of poker with PT and PAHUD running. This seems to happen when PAHUD is pulling the stats up for a given poker table (so, it usually happens when I first open new tables). Sometimes the tables lag badly and/or the sound stops working for a short period.

FWIW, I have 2GB of RAM and my hard drive has 300+ GB free. I run Windows XP. I have recently compacted my hand histories, if that makes a difference.

Any help would be much appreciated, thanks.
