2011 Every command an "Unknown command"

[Sinc]

Bizarre problems with C3D 2011 continue.... 

This time, I created four Cogo Points and then tried to "Export Points...".  Nothing happened.  Then I tried switching to another open drawing, and now I'm locked into that drawing.  Every single command I try to run - including "Open", "Close", and "Quit" - returns an error message from C3D that it is an "Unknown command".  Nothing left to do but the old three-finger-salute and kill from Task Manager.

The number of inexplicable problems in C3D 2011 has been rather disappointing, after the steady improvement up to C3D 2010.  And while I haven't tried using C3D 2012 in production yet, in my testing I seem to have hit even more bizarre problems in that release than in 2011.

I'm at the point where I have absolutely no intererest in new features...  I'd just like a reliable program that doesn't leave me hunting down bizarre behavior or dealing with crashes so often.
