Why are my shadows stuck? No matter what lamp I put in or how strong I make them the shadows on this file don't seem to be affected at all? 

I've tried changing the shadow settings but nothing really seems to be working. If I move any lamps the shadows on the model stay static in that they're completely unchanging and don't move in response to the changing of the lamp tool. 

It's almost as if the shadows themselves are painting onto the model but even if I strip the material the shadows are present on the model itself and are still unaffected by any change in lighting. 



Absolutely no difference in shading despite repositioning on lamp.

I'll post the file as an example so whoever's curious can take a peek. Here's the file
You switched Maximum draw type to Solid. Set this back to Textured



And also note, that this type of lamps must be rotated, to see the effects.
