mmkay well i have a batch of photos that whenever i try and edit them on iphoto simply wont load. everythings fine with scrolling through and looking at them and everything but when i try to go and edit a photo nothing will happen. or more appropriately it will try and go to the editing screen but never can. i'm not sure exactly when this started but i know i have worked with these photos before and everything was fine, and it is also just one batch that ive had issues with. all of the others i can edit with no problem. so help please ^.^
