What's wrong here??

I am trying to make an opengl framework by first creating a window with DC then adding on from there. The window creates and closes fine, but when I move the cursor oven a border so that it changes to a resize cursor, then move the cursor into the window, it remains as the resize cursor. This isn’t really a problem - just an iritation. The following is the source code thus far. (only 100 lns) Please could someone load it into VC++ 6 and tell me whats wrong. Thanks:

#include <windows.h>
#include <stdio.h>

bool keys[256];
HDC hDC = NULL;

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevinstance, PSTR lpCmdLine, int iShowCmd)
{
HWND hWnd;
MSG Msg;
WNDCLASSEX wc = {0};
DWORD dwStyle = WS_OVERLAPPEDWINDOW;
DWORD dwExStyle = WS_EX_APPWINDOW | WS_EX_WINDOWEDGE;

//Initialize the Window
wc.cbSize			= sizeof(wc);
wc.cbClsExtra		= 0;
wc.cbWndExtra		= 0;
wc.hbrBackground	= (HBRUSH)GetStockObject(BLACK_BRUSH);
wc.hCursor			= LoadCursor(NULL, IDI_WINLOGO);
wc.hIcon			= LoadIcon(NULL, IDC_ARROW);
wc.hIconSm			= LoadIcon(NULL, IDI_WINLOGO);
wc.hInstance		= hInstance;
wc.lpfnWndProc		= WndProc;
wc.lpszClassName	= "My Class";
wc.lpszMenuName		= NULL;
wc.style			= CS_VREDRAW | CS_HREDRAW | CS_OWNDC;

//Register Window with Windows
RegisterClassEx(&wc);

hWnd = CreateWindowEx (dwExStyle,
					   "My Class",
					   "Title Bar",
					   dwStyle | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, 
					   50,
					   50,
					   300,
					   300,
					   NULL,
					   NULL,
					   hInstance, 
					   NULL);

hDC = GetDC(hWnd);
ShowWindow(hWnd, iShowCmd);
UpdateWindow(hWnd);
SetFocus(hWnd);

while(TRUE)
{
	if(PeekMessage(&Msg,hWnd,0,0,PM_REMOVE))
	{
		if(Msg.message == WM_QUIT) break;
			
		TranslateMessage(&Msg);
		DispatchMessage(&Msg);
	}
	else
	{
		// Do all the hardcore computational stuff here  [img]http://www.opengl.org/discussion_boards/ubb/smile.gif[/img]
	}

}


ReleaseDC(hWnd,hDC); // Releases the memory of the HDC
DestroyWindow(hWnd);
UnregisterClass("My Class",hInstance);

return Msg.wParam; // And we're out

}

LRESULT CALLBACK WndProc (HWND hWnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{

switch(iMsg)
{
case WM_CREATE: break;
case WM_SIZE: break;
case WM_DESTROY: case WM_CLOSE: {PostQuitMessage(0); return 0;}
case WM_PAINT : break;
case WM_KEYDOWN: {keys[wParam] = true; return 0;}
case WM_KEYUP: {keys[wParam] = false; return 0;}

}

return DefWindowProc (hWnd, iMsg, wParam, lParam);
}
