Hello, I just recently switched to Mac and I am having some problems maybe someone can help me with. 1.) iPhoto has reduced my photo collection by almost half. Yesterday all the photos in my library worked fine. Today, when I opened up iPhoto, some of them give me an error saying they might be corrupted, other just dont respond at all, as if they dont exist. This is very very frustrating. 2.) When I have a Firefox window open, and I click on the firefox dock icon, should another browser window open for me?? I thought it was doing this earlier, but now its not. And when I have a chat window open in Adium, and someone signs on, I click on the dock icon, but the contact list wont come up. If anyone can help me, or tell me what Ive done wrong I would really appreciate it.
