inspect std::vector, on debug

Question

Hi, I am using Visual Studio Express 2012, on Windows 7.

Usually it is quite ok, and debugging is ok too. However , sometimes, when I am debugging, and using structures of std::vector type, I can not inspect the vector, directly, via a Variable Watch, or, by directly hovering over it, with the mouse pointer.

 

For example, I have a vector:

 

std::vector<std::pair<int, int>> homePoints;

which I CAN inspect, by hovering over it:

But I also have a vector:

struct match{
		std::wstring szwHomeTeamName;
		std::wstring szwAwayTeamName;
		int iHomeTeamScore;
		int iAwayTeamScore;
		std::wstring szwTimeAndDate;
	};
	std::vector<match> matches;

which, for some reason, I can't inspect in the same way, see this:

C

it seems that it sometimes works, for some vectors, and not for others? Why?

Thanks!
