mate problem after upgrade to 22

[Frank McCormick]

Upgraded my 21 system to 22 this morning...but using the script 
fedora-upgrade not
anything else
All seemed to go well...after reboot I went into my mate desktop and 
discovered
the panel at the bottom of the screen is not displaying. A quick check
showed it was loaded and seemingly running. Google didn't find
anything relevant.

Does anyone have a suggestion ?


Thanks
