custom ATL Control Property Page won't display VC++ 7.1

I'm creating a custom ATL control using VC7.1.  The custom property page
displays correctly using the ActiveX Test Container tool and draws correctly
in the test web page.  The property page shows up in the VC++ 6.0 resource
editor as well.  However, after placing the control onto a dialog box in the
resource editor with VC++ 7.1, the Properties display goes blank for all
controls on the dialog box, and right clicking on the custom control and
hitting Properties does nothing.  No error messages pop up during all of
this.

I've googled for hours to no avail.  Any help would be appreciated.  If this
is the wrong newsgroup for this topic I apologize, please point me to a more
appropriate one.

I solved my own problem, so I figured I would post the answer for archiving
purposes.  When creating the control I had checked Custom interface, not
Dual.  Recreating the control with Dual checked solved the problem.
