The panel in svn has odd demensions and behavior. This is on an xinerama machine, the best way I can show the problem is through screenshots, as there are very few video players that support my high resolution.

How it looks due to autohide.

This is after I have the monitor shown with mouse over.

This is after a single click anywhere on the panel. This click is completely useless other than clicking to resize it to a sane size.

So, essentially it takes two clicks to make anything happen at the moment. I am unsure of the rhyme/reason for the panel blow up. Please let me know any other information I can give that will help.
