How do you bring up the VB or C# Call Stack window to debug?
It's in Debug -> Windows -> Call Stack, also available with Ctrl+L
Used to be you could right click in the bottom somewhere to bring it up - I guess they made it more explicit. However, keeping it in Windows option only under the Debug Menu option was kind of hard for me to find, for some reason.
I think it would make sense to provide all the Debug windows under
View -> Other Windows -> Debug
