When I run guide in matlab it opens a blank all gray window. Whats going on?

When I run guide in Matlab, the window that opens is completely grayed out with a title "GUIDE quick start". I am running R2012b in Ubuntu 12.04.2 LTS. Has anyone else run into this problem?

UPDATE 1

So I just discovered that if I press enter on that first blank grey window then it opens the Layout Editor window and everything seems to be fine. So I am guessing that on that first screen there is just an OK button (which I cannot see) so when I press enter it is like clicking on the OK button.

UPDATE 2

I built a quick GUI and there are issues. I can create axes and buttons and sliders on the layout tool. However, when I run the GUI tool it only displays the axes, the buttons, sliders are not there.

I'm having the same issue on Windows x64. Matlab R2012b.

What JVM are you running? Is it stock or 1.7?
