Same problem here on an Asus P50IJ. Once I press the backlight function keys I am also unable to use any of the other function keys like volume as well. Its as if it causes the whole system that deals with the fn keys/notification to lock up or slow way down. Adjusting the slider in the volume control applet still works however. Also the Brightness Applet does not work either. It will open but when the slider is clicked it just disappears.
