Oh I get it! :)
I hate this!
1st but I don't thick this is your problem... in full screen mode down in the lower right you cant see the frame's option.
ok, so you open a project and for me it's always the console view takes up the full screen, well kind of... ha!
anyway. To fix this (if it's your issues) you need to in the upper right corner reduce the "Track view" then drag the other views into the Track view. Depending if you are docked on the top or the bottom, grab the undocked view on the top or bottom... rollover the area where it would normally be docked. Look for the blue bar to light up then let go. It should then dock the view into the Track View.
I hope that makes since! :)
EDIT: I should say that with this "bug" you will need to dock the view ^ in order to fix the bug. Then you can float if you want to.
peace!
