I wasn't having this problem until right after doing several uninstalls/reinstalls of VS 2012 to resolve an unrelated problem. But now I've got it. I've seen that others have experienced this, too. Is there a solution?
An "update" of VS 2012 from the Microsoft web site didn't help.
What I have installed now is 11.0.61030.00 Update 4
