It appears to me that, although I do not have the recent MRU check marked to delete that they are being deleted anyway.
I am Running Vista & MS Office 2007. In MS Word, just for example, there are files listed in the "Most recently used" list box. I go run CCleaner and now there not there anymore. Refer to the attached screen shot. The screen shot also shows the version# of CCleaner I am currently running in case you need it.
Am I missing something here???
