Every once in awhile in full screen my controls will go transparent when viewing video or photos in both 2d and 3d when moving the mouse. The controls when transparent work just fine and are easily seen, just the background of the control bar becomes transparent. I would like this to be this way all the time. I can find no setting in the settings to accomplish this. And if watching video and I switch to another video the transparency disappears. The translucency is random, all of a sudden its there and sticks. It's great for 3d because you can still see the top and bottom of the video or image.

So how do I get this transparency to be active?

Another note: several versions ago, maybe 6 or 5 or 7 you could undock the controls. What ever happened to the feature?
