Game starts with odd view of KSC, and is unresponsive

[Balrog]

Sometimes, after I load a saved game, KSC shows up at a vantage point near the ground by the VAB. Pressing ESC does nothing, pressing the Pause Menu button does nothing. Mod popups all work OK. I have to close and re-launch the game.

This glitch has been in the game for a very long time (I have definitely seen it in .99 and i think back in .25). Restarting ksp fixes it 99% of the time.

You can fix it when it happens by alt+F12 then click "Show Input Lock Stack", then "Clear input lock Stack"

It can be caused if you alt tab out when its loading, so try to avoid that. 

I had thought it was fixed since I used to get it all the time (my fault for tabing/using 2nd monitor), but not once since 1.1.
