Problem deleting files

I am having problems deleting files from my SuSE 8.2 system. If I do an rm on the command line it is deleted fine, however when I do a Shift+Delete in KDE 3.1.2 it does not delete no matter what I do. I have even checked to find where it may possibly save a file the same size as the file that was deleted. Any help would be appreciated. Thanks! NeoFax
