Kerbal Space Program

I can't place maneuver nodes while on a suborbital path shortly after launch. Time warp is also unavailable. When running mission to Minmus maneuver nodes pop on to the background in between the Mun and escape. Predicted encounters are not shown. Setting targets often doesn't work. I've had this since 1.1.1. The game does not crash, but it usually destroys my missions. I can get time warp to function by pressing map + warp at the same time.
