Don't quite know how to describe what has happened. Went to hop on the computer (g4 powerbook, tiger) and turn on my wireless. My wep password was no longer there. Noticed that my doc and everything else has pretty much reverted back to factory settings. However, I still have all my stuff on the hard drive. For example.... I hit iphoto and I got the welcome iphoto screen. Wanted to show me all about iphoto and so on. It seems I still have all my pictures except they no longer are separated as rolls. Just one big library of pics. The desktop is the same but my dock is back to the original. I am running low on hd space. I have a gig left. Does anybody have an idea as to what has happened?
