I just got my imac 21.5 a week ago, and now already a problem. It was working fine until now. I have been copying and pasting pictures and avatars from forums onto Microsoft office (office mac 2008). And tonight I got the dreadful color spinning wheel when I tried to copy more. I wouldn't go away after 10 minutes, so I restarted the computer. I reopened office, and it still had the wheel. It keeps saying it has to close. Why is this happening? Is it bad to copy and paste? I do have Apple care protection- how late do they take calls?
