To start off, I'm playing on Linux under Wine.
I was in the factory, and had just picked up an item (the Precision Assault Rifle). I inspected it to see how it compared to my other guns, but either before closing the inspection window or as soon as I pressed the key to do so, the game froze and had to be killed.
No idea how to reproduce; unless it's some problem with the Precision Assault Rifle data I can't think of anything else out of the ordinary about the situation - I had used that window many times with no problem, and doing so now causes no problems.
