Individual string values will show up if you store a reference to a .NET string in an object reference variable, but for a List<String> it will only show the typename (i.e. List<String>). One thing you could do is create a new class derived from List<String> that overrides ToString() (it's a virtual method) and returns a string showing all of the values, then they will be displayed in the TestStand variables view. Or you could just debug into a code module which returns or takes this list and look at it in visual studio.
Hope this helps,
