Hello:
First I loved your CCleaner product and have used ist since it's interduction.
I loaded the latested beta of defraggler. Ran the full defraf option on my home desktop, Windows XP Home SP2 fully patched. After the defrag completed I attempted to run another analisys of the c drive. I received a error telling me i did not have sufficiant rights to execute defraggler.
I insured my account had administration authority, it did, and attempted again. Same error. I rebooted the machine, and was able to the run Defraggler, however after I ran the analize function again, and attempted to defrag specific folders, the folders, the error occured again. If I reboot it works again, but it just seems odd that a permissions error is present to execute the program.
Just thought I would mention this small issue to be researched.
