If you using a winch cable in rope, space walk safety. I had to do. I have too low FPS in linux. NOTICE!! Do not go into the airlock when the winch cable is on the Kerman back. Freezes the game. KAS breaks down. You can not get even the space center, but you will have to kill the entire game. How to get fix this problem. yes you are close. 1. get Kerbal spacewalk. 2. attack winch cable in back kerbal 3. open winch gui 4. go back in vessel. 5. Winch menu disappears all the buttons, and it can not be closed. The game refuses to quit.
