I have a Powerbook G4 and I am running OS 10.3.9. About 2 days ago when I started up my computer all the icons on my desktop are gone, including my HD and the menu bars at the top. The top menu bardoes show up when I open an application from the docking station, but disappears again when I close that application. I know my files still exist, because I can open them in various applications, I just can't see them, or access them thru the finder. I have tried disk repair, I have booted from my instal disk and run a hardware test, nothing seems to help. Any ideas?
