I upgraded to 6.51 Build 3162 a few days ago from whatever the last beta was. I spend most of my time in the search tab and everything I normally do has worked (and worked faster, thank you!) with one exception. Hide Old is not hiding the files any longer, at least in the Search tab. I haven't tested it in the groups tab. When I search, the new files and the old files appear. I can hit delete and files will disappear but only until I do the same search and then I get all results (deleted or not).
Suggestions? Thank you.
