	[...stuff deleted...]

	Note: this is the classic case of a handle mismatch.  If you
	use #define STRICT when compiling, the compiler will catch
	things like this.  All of these things are just UINT without
	STRICT, but with STRICT, they become pointers to various
	structs.

		#define STRICT		//USE IT!!!!!
		#include <windows.h>
