I just wanted to add that you're not the only person who's experienced this problem. It worked after I upgraded to kde 3.1, however, soon afterwards it suddenly stopped working.
Any idea what could be causing this?
P.S. - I checked the KDE forums and apparently, there are a few other people running RH8 and have just upgraded to kde 3.1 that have the exact same problem. Someone suggested an rpm incompatibility with RH8 but there doesn't seem to be a fix.
go to
www.kde.org and go to the forums, and then search for "taskbar".
