Thanks BF but I do a regular scan with Webroots Spysweeper and use DiskKeeper to keep my hard drive optimized every night.

I don't have any Spyware or virus.

My Java machine is java.

I seem to have found some further info on this problem.

If I leave it running for 30 minutes or longer (approx) and come back the program is running smooth and fast.

Thanks for you help...any more ideas?
