No, the keychain thing doesn't, it was just a weird, annoying thing. Could not move anything from one folder to another without entering a p/w. I finally started to just unlock folders I was working with. It's probably something she did. But it didn't go away when I ran Disk Utility which should have fixed permissions, right?
Repairing Permissions with Disk Utility only repairs system and application level permissions.
As additional protection against nefarious activity by malware or hackers, Apple has greatly tightened the requirements for authorizing installation of apps and moving of any folders or files beginning with Mavericks. Get used to it, those constraints will only become more stringent in the future. We all love to brag about our Mac's relative immunity to malware, but as has been noted before, "there aint no free lunch". Part of the cost of that lunch is the requirement to authenticate the change and/or movement of system files and applications.
