Gnome-panel trouble with odd FC2T2

[Wayne Whitney]

Hello,

I updated from FC2T1 to FC2T2 by mounting the .iso files and doing a
massive "rpm -F".  Not the proper method but it usually works.  However,
this time it has killed gnome-panel.  Whenever I try to start gnome-panel,
it fails with the error message "I've detected another panel already
running, so I will now exit".  Obviously I have checked and there is not
another gnome-panel running.  I tried creating a fresh test account, and I
see the same behavior, so it is not specific to anything I have in my home
directory.

Any idea what causes this?  I would gladly reinstall FC2T2, but am stymied
by the following:

The stock FC2T2 boot.iso has the "hdc using ignore" problem on my machine.
The development boot.iso doesn't recognize the FC2T2 discs.
I can't find development .isos.

Any help would be appreciated.

Thanks,
Wayne
