UTStarcom PPC-6700 / XV-6700 / HTC Apache

I have installed spd pocket plus and it slowed down the unit so much it wasn't usable. When I received a call or turned the power button on it would take 10 to 15 seconds to answer or for any button to work. Anybody else have this problem and might have found a solution? I have used the program before and a samsung i700 and never had this problem so I believe it is a windows 2005 problem. Any help is greatly appreciated.
