Specifically, don't use 9.1 KDE Help Center, as opposed to the Gnome help that appears in the menu system, from Gnome 2.4. While trying to figure out the changes to Samba, I needed to access the online manuals. I created a launcher in Gnome using the command "khelpcenter". This appeared to work as normal and I was able to create an index, search the manuals, and read the chapter on Samba. As some point, I had occassion to move the khelpcenter window. I noticed that portions of the icons that had been covered by the window didn't refresh. I move the khelpcenter window around some more and was able to erase all my desktop icons. Further... I closed the khelpcenter window but the icons did not refresh. I opened Mozilla. It's window appeared and disappeared when I closed it but the icons didn't refresh. I logged out of the Gnome session and logged in again but the icons didn't refresh. I logged out again and did the ctrl-alt-backspace trick but when I logged in again, the icons didn't refresh. I logged out again and rebooted the system. This time, when I logged in again, the icons were there. However... You should never have to reboot a Linux system, especially to correct a problem in a window/display manager. I'm asking that at least a couple of you try the above and see if you discover the same problem. If this is a common problem, as opposed to something stupid that I did, I'll submit a bug. If you could also give me a suggestion on which bugzilla to use, I'd appreciate that as well. Thanks for any assistance. Don Henson
