My Microsoft Word was working fine when out of the blue, if I insert a picture from file, I can't see it. I know it gets inserted because:

A. There's an outline around where it should be

B. When I click on it handles appear and

C. If I open the file on a co-workers computer I CAN see the picture

but on my computer it's just solid white inside the box. So it's there but I just can't see it for some reason. I have tried inserting many different pictures including ones that have worked fine and shown up in the past. Anyone know how to correct this? 

Thanks
