Englishmen--thanks for replying again and explaining your previous post. Yes, it is the case both 1) that the quicktime mru list does not show up when I analyze and also 2) that CCleaner is not cleaning out this list in quicktime itself. I guess, as you say, it may just be a problem with an updated version of quicktime that CCleaner is not configured to deal with (I'm using version 6.5.2).
