Hover in design tree doesn't highlight parts in display window anymore

Myself and a co-worker just started using SW 2011 on new machines and have found that when we hover over planes in the design tree, those planes are no longer highlighted in the main window. We are using Quadro 4000 cards, but are not sure if this has anything to do with it. Also when we want to start a new sketch, it normally showed the planes to choose to put the sketch on, but it doesn't do that anymore either. We do have "Dynamic highlight from graphics view" turned on under Display/Selection, as well as "Dynamic Highlight" under FeatureManager. Any ideas???? This is really frustrating to lose features we use all the time!
