c# - Datatips (mouse hover over variables in debug mode) not working in Visual Studio 2012 / Win 7 64bit

Question

When I hover my mouse over a variable when debugging a C# app in Visual Studio nothing popups. I expect to see the value of the variable (aka datatips). I'm running Visual Studio 2012 Ultimate (trial edition) on Windows 7 64bit. Does anyone know what may prevent them from showing?

Things I've tried to no avail: - Reinstall VS - Search for an enable/disable setting but there doesn't seem to be one

I can see the datatips correctly with the same C# project on Windows 8/64bit with the same version of Visual Studio.

THis helped me: you need to open in VS Tools | Options | Debugger | General and enable the flag [Use Managed Compatibility Mode].
