No Gnome!

[Rev David Peel <revdpeel ap com au>]

Dear All,
When I changed from RedHat 6 to 6.2 I lost my Gnome.
I currently am using KDE but like Gnome, when I use switch desk I end up 
with the X window, just grey with an x cursor. When I Ctr-Alt-Bkspc to the 
console I read the following messages

Gtk-CRITICAL ** : file gtkwidget.c : line 4254 (gtk_widget_push_visual): 
assertion   'visual !=NULL' failed
Gtk-CRITICAL ** : file gtkwidget.c : line 4238 (gtk_widget_push_colormap): 
assertion 'cmap !=NULL' failed.
Gdk-imlib: Cannot find palette. A palette is required for this mode.
Gdk-CRITICAL** : file gdkwindow.c: line 1406 (gdk_window_get_visual): 
assertion  'window !=NULL' failed.
Gdk-ERROR ** : X connection ttto :0.0 broken (explicit kill or server shutdown)

I have located the palettes using the find in the file manager. They do exist!

Is there some way that I can configure  the relevant programmes to point to 
them or can Imove them to an appropriate directory.

Or maybe I have to do something more basic.   Where can I find a SIMPLE 
guide to what files Gnome needs, where they need to be and how I configure it?

Please & Thanks
David Peel
