Cinnamon won't load panel.

[Frank McCormick]

The past week or so I have been having trouble with my Cinnamon desktop 
on Fedora 19.
The panel is not loading, and it **seems** like the wallpaper is also 
not loading, although because I run 2 gdesklets, the proper background 
can be seen on them. The rest of the screen is black except for the 
desktop icons. Once in a while if I logon to Cinnamon 3 or 4 times in a 
row the desktop will come up properly but other times it refuses to load 
properly. I also run Mate and XFCE desktops and I am wondering whether 
there is a conflict somewhere.

Is anyone else experiencing this ?  Any suggestions would be appreciated.
