After running CCleaner, if I run tree size free it shows files in the recycle bin. In this case 0.3GB. Uninstalled the latest version and installed version 3.08.1475. Ran analyze and it found the 0.3GB and deleted it.
Keith - Is it possible that this only happens when there's a folder in the recycle bin? There's a thread started back in October which detalis a problem emptying the recycle bin under XP which was initially confusing since it only fails when there's a folder in the recycle bin. The good news is that a manual recycle bin "Empty' cleans up the incomplete results left behind when CCleaner attempts to empty a recycle bin containing a folder.
