I'm a new mac user and I'm totally lost when it comes to troubleshooting my problems. I've been trying to access my iphoto application for the past couple of days and it isn't working as it should. The application is open and when I place my mouse in a corner of the screen, the iphoto screen shows up in my boxes view, but I'm unable to click on it. As soon as I click on the screen it disappears. So the application is open and the options bar appears across the top of the screen, but I'm unable to view it normally. Please help! Any suggestions of what I could do to fix this would be greatly appreciated! Thanks!
