desktop management issue SUSE 10.0

I was trying to get xplanet working, and when I went to advanced background settings there were 2 entries existing that I had not put there. KDEworld and kwebdesktop. My entry for xplanet was below those 2. When I tried to remove kdeworld I got an error message saying: unable to remove the program: the program is global and can only be removed by the system administrator. any clue how to remove them??? I looked all over the YaST menus and I am unalbe to see where I can delete those entries. -- Paul Cartwright Registered Linux user # 367800 X-Request-PGP: http://home.bellsouth.net/p/PWP-pcartwright/key.asc
