[GD-Windows] RE: [GD-General] [GD General] Windows in .NET :(

(cc'ing the Windows list and removing the general list)

You haven't specified a WNDPROC for your window class.  That might be
one lame reason. =20

In any event, it's a pretty safe bet that oodles of apps calling
RegisterClass were compiled through VS.NET before it shipped.  You
should probably have another look at your code.  Try building a DX
sample app, and compare their setup code against yours.
