This is a problem that's appeared for me in the latest version of KSP. When I start a career game, everything is fine for a while, but as I get further through it and have a few landing sites & space stations something odd happens. The first sign is that the controls freeze when I switch to a new ship. I can't change the view, control the ship or move to the map mode but I can return to the space centre and when I do I get this view of it: When this happens I have to close the program through windows as it's now almost frozen. I can revert to the main menu but then it's completely frozen with no way to close it through the game itself. By this stage in the saved game it takes five or six times to load it as when I open the saved game it usually goes straight to the screen above, meaning I have to quit out and start again. Other saved games load first time until they too get too big and lock up. I've tried to track it down to one mod but I played a game with just mechjeb, Kerbal alarm clock, precision node and Docking Port Alignment Indicator and it still happened.
