Guys - As a reminder to other new users (such as myself), you must have a corresponding install of the Microsoft Platform SDK installed on you machine to have all of the required .h and .lib files required to run ALL of the Cuda SDK examples.
In order to run the OpenGL samples, I had to copy the required files from the /inc and /lib directories of the Microsoft Platform SDK into the Cuda SDK /inc and /lib directories. I think I could have just added the Platform SDK path to the build directives, as well.
I ran into trouble when I uninstalled MSVC Express 2008 (which worked fine with Cuda 1.0) and installed MCVS Express 2005 - without the corresponding platform SDK.
Thanks for all the help on the board!
