Hello all,
My thumbnail database had somehow become corrupted and when I ran CCleaner's clear thumbnail cache function, nothing happened. I realize that you can use Disk Cleanup to clear that particular cache and I did that (Disk Cleanup showed an 81MB file and CCleaner showed 0KB), but the fact that CCleaner didn't do anything leads me to believe either something is wrong with my computer or with CCleaner. I've also noticed that it doesn't clear the menu order or window size/location cache. Is anyone else having these issues?
