If the class fails to register even after you have tried again after
rebooting, there is a problem in your code.
I can't see it right now though, from what you've given me, try going
through all the things that will happen when you start the program (in order
in the WinMain function + the things in the WM_CREATE, WM_SIZE and WM_PAINT
cases).
