Realistic View not operating correctly

Hi,

We have 2 machines running AutoCAD 2014.  We both use our machines for the same thing, both have the same settings (I set them both up identically).

I use my machine like I intended for it to be used, my co-worker uses it bare bones (she doens't render or use any of the other views except 2D wireframe, normally).

I have our CAD Block library set up so that all the blocks are already finished (meaning, they all have materials added to them) so we don't have to do this to each block in a drawing (saves a lot of time).

I use Realistic View everyday, never have any issues with it not working properly (minus some materials dissapearing upon block insertion from time to time, another issue entirely though).  Today, my co-worker had a need to use Realistic View and when she types in SHA, R .. instead of a view that shows the materials her background turns a dark gray (instead of staying black) and all the blocks turn either gray or black (sometiems the parts & pieces are all one color, some others have mixed black/gray).

I've gone through all the settings (under both Realistic View Manager & OP) and they are all exactly the same as mine, line by line.  Our computers are identical (graphics cards, processors, even the monitors).

This is about to drive me nuts.  Anyone have any suggestions on what could be amiss here?  I'm stumped.  I'm guessing she has accidentally mis-typed in some command at some point, but I have no clue what it could have been, and I'm not having any luck googling our particular set of "symptoms".

Thanks in Advance,

J
