QuickInfo shows a single letter instead of full variable name

Hi,

I have an isolated shell application based on VS2010 shell. The mouse over on a variable in debug mode gives the name of the variable and the value.

Now, I have ported the application to isolated shell VS2013, now the mouse over on a variable is not identifying the entire variable name instead identifies only the single letter in the variable name.

There has been no change in the source code.

Is there any special handling required for the new isolated shell?
