Compress context menu

Hello, I have been using suse 9.3 for about a week. I upgraded from 9.1. Has anyone else noticed that the "Compress" context menu (in Konqueror) shows up intermitantly? Sometimes, it will appear, allowing me to either compress a directory or uncompress a tar.bz2 (which it created) or even a tar.gz (which it has also created). Anyone know where/how I can also make "Compress" always appear in the content menu? Thanks, Alvin -- Please reply to the list.
