Thanks for any help.
Running Windows 7 pro 64-bit on a Pavilion 64-bit computer.
I have never touched the settings since day 1. So they are as
Piriform set them. I also use defragger on a Windows 7 pro 32-bit
Dell and it works fine.
Maybe I should try an earlier version to see if that solves the problem.
Where can I find an earlier version of defragger
