Problem with editing in Visual Studio Express 2012

[kintaro26]

Hey there,

say my program looks like this

#include "std_lib_facilities.h"

int main()
{
	cout << "Please enter a floating point value: ";
	double n;
	cin >> n;
	cout << "n == " << n
		<< "\nn + 1 == " << n+1
		<< "\nthree times n == " << 3*n
		<< "\ntwice n == " << n+n
		<< "\nn squared == " << n*n
		<< "\nhalf of n == " << n/2
		<< "\nsquare root of n == " << sqrt(n)
		<< endl;

	keepwindow_open(); //error
	return 0;
}

Notice the error, a "_"is missing.
Now, I'm using Visual Studio Express 2012 and when I try to add a "_" between
"keep" and "window" it would look like "keep_indow_open();" instead of
"keep_window_open();".
Rather than adding new characters it substitutes them with characters that I type in.

Another example:

cout << "cpluspluscom"

Oh, wow. I forgot the dot, let's add that real quick.
Oh, no, you can't. Now it looks like this: cout << "cplusplus.om"

How do I disable this function?
I remember the 2010 version not having this "problem:.

Thanks
