Photo Preview and Contacts won't show anything after OS X 10.9
After installing OS X Mavericks I got this errors...
My photo preview open when I click on a photo, but it won't show the picture.
When I open my Contacts, it starts... Nothing is shown :-(
In iPhoto the Slideshow function only show the first picture. It does not show the next picture after 3 sec. and I can't choose the next picture on the arrorws. Nothing happens, when I click on one of the arrorws.
Does anyone have a solution on this errors?
MacBook Air, OS X Mavericks (10.9)
