Using SW 2014. Has been working fine. Now I can't delete any features in my model once I've put them in.

Have a shaft I'm drawing with a 1/4 radius groove around it. When trying to delete this it gives me an error and freezes.

What's crazy also is that the error message is off the screen and I can't read it. Can only see very edge of message box.

This is driving me crazy. Right now I've be suppressing features that I can't delete.

Any input or fix would be greatly appreciated.
