Disappearing bottom taskbar, Fedora 20 Beta

[Scott Castaline]

With the Alpha release I did not notice this happening but with the Beta 
release using Gnome-Shell-Extension-Taskbar v38 (set for bottom bar) the 
bar will appear after logging in for a moment and then disappear. If I 
do an alt-F2, r, enter the desktop will restart with the task bar 
present until I click on one of my favorites icons, when it will 
disappear again. If I wait a while and repeat the above steps it will 
then stay on. Occasionally it will come back on its own. Has anyone else 
seen this? If you have and got it working, what did you do to resolve 
the problem?
