Not Returning to Space Center or Tracking Station, or Quitting to Main Menu

[Titusspqr]

Over the past few days I have come across this bug several times. Sometimes, when I want to save something e.g. a base, space station or rover, when I press Space Center, Tracking Station, or Quit to Main Menu, it does the grey-out that tells me that I've pressed the button, but it does nothing. This is particularly annoying since I cannot do anything other than reverting to launch or VAB. F5+F9 or Alt-F5+Alt-F9 don't work either. It doesn't appear to be triggered by anything. The only mods I play with are the Making History Expansion and OPT Spaceplane Parts 2. In the Alt-F12 menu, it tells me: Exception:ArgumentOutOfRangeException Argument is out of range. Has anyone experienced and/or fixed this problem?

Thanks in advance.

Wierd. Do you have the correct versions installed? And all dependencies? 

If these does not help, can you try a new save or a new install?

[Titusspqr]

Yes, and yes. I don't particularly want to start a new save because I have several interplanetary refueling stations and I would like to use them. Also, I don't tnink that this is related to ship count. I have only 10 flights in progress in thuus save but have 47 in my only other save.

i had this same problem after installing ubio welding, never figured out the problem, hopefully it doesnt come back.

does their happen to be alot of things near the active vessel when you try to use the menu? i assumed on my end that it happened because i had a gob ton of random parts floating around randomly in physics range.

 I originally thought that as well, after an explosive stage separation. I had an Apollo-style rocket, the decoupler and sepatrons made things explode, so I turned the service module around and docked, but then I couldn't leave and had to revert. But I don't think that this is the case. I landed on Minmus but then wanted to build a VTOL aircraft, but agian I couldn't leave even though the only parts around were my lander and the mothership in a 20 km orbit.
