Why do I see only the border of the Firefox window when I project the image wirelessly?

I am trying to use FF on a Dell Latitude latop to an Infocus projector using LiteShow Manger to connect the two- the connection is wireless. I have no problems with establishing a connection nor do I have any problems with seemingly any other piece of software on this system as far as the image being displayed on the screen. FF will open properly with no hesitation or error message and the home page is displayed just as it is seen on the laptop. This is the weird part....the image on the laptop is normal and changes with the clicks of the mouse or use of the keyboard, but the image on the projector will stick and freeze on the initial image. I can see the mouse move across the FF window but no changes are displayed on the projected image. The problem is isolated to the area within the blue border of the FF window. To sum up the image will not update past the initial page image in the FF browser window.

I ran into the same problem with a user. System would not draw the screen when projecting FireFox to an InFocus 1501 wireless projector.

Started FireFox in safe mode and it worked fine, but would not work in regular mode, even with all the add-ons disabled. System works just fine with IE or other applications.

Note that this just applies to FireFox 5.x and doesn't appear to be an issue with older versions.

Solution: Tools > options > Advanced > General tab > Hardware acceleration Turn off hardware acceleration.
