I have been renning CCleaner and Defragger on my Compaq AMD Athalon 63 3500+, Win XP SP3 2002, for a long time, no problem Ever. My son recently down loaded Defragger, on a newer, similar system running Vista. It defrags to 30%, then seems to be working but 12 hours later is still at 30%. Are there Vista problems, or should I reconfigure ?. I am running rev. 1.10.143, so is he. Please help if you can. Best Regards, Larry
