KDE-Forum.org

I upgraded to Fedora Core 6 last night and now when I VNC in i get what I would call ghosts or residue of previously opened applications which become part of the desktop back ground until I Change the Back ground or until i reboot (see attached screen shot). They go away when I do a refresh desktop with out any background image set.
version inf:
Qt: 3.3.7
KDE: 3.5.5-0.2.fc6 Fedora-Core

I will see if they are present on the screen later today with out VNC ... I do not have Physical access to the box right now.
Any suggestions would be useful.
