I just signed up for a free trial of the .mac service. I got some photos up through iphoto, but I'm having a lot of difficulty adding avi files to my idisk so I can put them on my homepage. When I try to copy a file to my idisk it copies, but then something happens at the end where it says it is closing the file. This message stays up for a couple of minutes. When I go to my idisk nothing is there. Why? Thanks.
