My iPhoto won't open
I click on my iphoto icon and it comes up with the coloured 'thinking spiral' and won't open. I try to go into other icons while waiting but it will not let me into those after I have opened iphoto version 9.4.2. It seems to be freezing everything else and the only way to close it is by shutting down the computer :/ I have a Mac book pro
MacBook Pro (17-inch Early 2011)
