about a week ago I tried to access system preferences using the apple menu, and it wouldnt open, and then I noticed that the system preferences icon in the dock had changed to the simpletext icon. I could go to system prefs using that, but not the menu. Anyway, last night I accidentaly dragged the icon off the dock, and now I cant get to system prefs. Is there a way to restore everything back to normal? A restart didn;t help.
