I know I know..
I know I became paranoid when this happned to me. Heres what you do.
1) startup with OS9. Create a folder called "OS 9 dekstop" or call it whatever. (It has to be an alias of a folder containing all your desktop items)
2) Then place this on the OS X desktop which should be in your hard drive in the folder "USERS" it is called "DESKTOP".
3) Start OS X again.
