mouseDown Event / locationInWindows always returning (0,0)

Hi,

I've a strange problem  under 10.5,

I subclassed a NSView and declared in it :

- (void)mouseDown:(NSEvent *)theEvent
{         NSPoint p;

   p = [theEvent locationInWindow];
}

Under the debugger, the event is trapped and the function gets called, 
theEvent shows a correct mouseDownEvent type (1),
the protected '_location' NSEvent member contains the right mouse 
coord, window is not nil, everything is OK
BUT locationInWindow always return (0,0)
I browsed the mailing list before posting and tried to make the same 
thing in a window subclassing, same result

Has somebody a clue before I loose all my hairs? I'd appreciate a lot

Regards
Luc B
