Get Window Handle on Mac

Hi All, for a long time I've used this code to get a handle to the game window on Mac. I do this so I can work out where the window is positioned so that I can make the mouse cursor move in and out of the window nicely. However there's a fairly rare issues with it, which is that when the code is called, there's a chance the ANOTHER window (not the game) has the focus and so my code will screw up big time.

So my question is, can anyone help get a handle to the actual BlitzMax window created with Graphics w,h,0 please?

This code is in Objective C and is imported into my BMax code:

NSWindow* macGetActiveWindow(){
    NSAutoreleasePool *pool=[[NSAutoreleasePool alloc] init];
    NSApplication *myApp;
    myApp=[NSApplication sharedApplication];
    NSWindow *myWindow = [myApp keyWindow];
    [pool release];
	return myWindow;
}

Here's what I'm doing in Windows which is nice and safe for DirectX:

		?Win32
		If Driver=0 Then
			Local my_driver:TD3D7Graphicsdriver=D3D7GraphicsDriver()
			Local my_graphics:TD3D7Graphics=my_driver.Graphics()
			Return my_graphics._hwnd
		Else
			'Use unreliable method in OpenGL until I get better code.
			Return GetActiveWindow()
		EndIf
		?

So I'm guessing the Mac solution may be similar, and might require a module tweak...

Any help greatly appreciated as it'll help out a friend who's app is getting rejected in the Mac App Store at the moment, possible due to this code. Thanks!

Just bumping this in case anyone has solved it in the last year?
