Ok...got my 15" Powerbook back after my Superdrive died. Apple really has fast turnaround with hardware repairs. They didn't reformat my drive. What's weird though is everytime I download a file in Safari or Firefox it refuses to show up on my desktop. The only way of accessing the file is by using the Download window in the browser to "show in finder." The files are invisible. I cannot try directly opening a movie, txt or mp3 from within the appropriate program. Is there anyway to fix this?
