SubD face selection not working

Hi,
I am just learning to work with SubD. I learned very quickly to use Ctrl + Shift to select edges, vertexes, faces. I can select vertex and edges with no problem but when I Ctrl+ Shift + Click the middle of a face I get nothing.

I tried SubDFaceVertexToggle command.
Also SelectionFilterFaces command.
Im not sure what I am doing wrong.
I have installed Version 7.4.21067

Hi - does this also happen with a new file from a factory-default template and just a simple SubDBox?
-wim

Yes it does

Hi - could you please run the Rhino SystemInfo command and copy-paste the result here?
And, just making sure, which display mode is your viewport in?
-wim

I was informed that it was in the wrong mode. I had it in Wireframe and it should have been in Shaded. That did it! Thank you for replying!
