I just installed 2.0.7 but there seems to be a problem. I'm getting windows removing themselves from the menu, most importantly the Delta-V and vessel info windows, and the only thing that fixes this is a complete re-install of KSP and all my mods. This seems to happen when I edit existing probe parts to contain the, MODULE { name = MechJebCore } Line so they function as Mechjeb cores, and then load a stock spacecraft containing one of the parts. But other than that I have no idea what's up.
