Since installing latest update (14.5.2), I am having trouble switching identities, Have latest version of Yosemite. When I switch to my wife's account, all is fine, but when switch back- (Microsoft Database Utility, switch to Main, and make default)- her information continues to come up with relaunch. I have to rebuild my main identity every time to get back to normal. I have even tried an older backup, but problem still exists. Permissions and preferences have been reset.
