Do you have the latest hotfix installed - hotfix 5 (build 4056)?
The only other thing I can think of is to maybe play with the hardware acceleration setting in the work environment (see attached image) but I am not sure if this will help or not.
No harm to give it a try - you can always set it back.
I remember I did have a problem once back in version 14 (not the same as yours - it was freezing in 3D) and I actually had to remove the video driver and install a slightly older one and that solved the problem.
Maybe that will work.
