KDE problem

I'm running RedHat 6.1. GNOME worked and continues to work (as well as
it ever did). KDE WAS working and I broke it somehow. Now it seems that
none of the buttons (icons) on the toolbar that run programs work any
more. There is momentary disk activity when a button is pressed but
nothing comes up. Buttons that bring up sub-menus still work inasmuch as
the sub-menus come up, but when you finally reach an executable and
invoke it nothing happens. None of the icons that used to appear on the
desktop (templates, etc.) appear any more. There is a "kvt" terminal
window that comes up and Netscape comes up. Both of them work; I can run
programs from the kvt window.

I have been messing around with the video and audio drivers recently. I
am now using XF86_S3SAV instead of XF86_SVGA, and the "oss" sound
drivers instead of nothing.

I LIKE KDE! What did I do?

Thanks, Ed.
