I've got a slight problem with my G4. It seems that ever since my last update to 10.3.8 in late February, I am unable to open or even find the system preferences panel. I cannot open it from the top/left apple or the finder, its missing under applications. The date and time on the desktop work but do not lead me to it. Also, right clicking on desktop and hitting "change desktop background" does nothing at all. How can I fix this problem?
