The MSDN article "OpenGL III: Building an OpenGL C++ Class" presents a 
different method for handling multiple OpenGL contexts. 

If you don't have a subscription to MSDN, you can view the article at the 
following location:

        http://www.microsoft.com/MSDN/LIBRARY/TECHNOTE

There are other articles about OpenGL in the same location.

The source code was written for Visual C++ version 2.0 and may need to be 
tweaked for Visual C++ version 4.0.
