I'm having the exact same issue. Three (3) of my most recent saves won't allow me to open the orbital map with the 'M' button. Pressing the 'Map View' button in the lower left of the GUI (under the 'Display Staging' and 'Docking Mode') brings up the orbital map but pressing it a second time leaves me in the without the ability to do much of anything (can't move around, interact with planets, etc). I, however have several mods, Kerbal Engineer, MechJeb, Astrogator, and HyperEdit.
