Hehe... a_super_hero: I've done it for you.... well sort of. You now have the option to 'Remove unrequired RSR thumbs' or 'Remove unrequired PNG thumbs' during the scan. This should help you to rid yourself of pounds of excess RSR thumbs. Basically, if you choose the new option, the thumbs will be removed if a thumb of the other type also exists for content.

I just removed about 100 such RSR's from my gash Poser 5 install!
