Hi,

I'm using a NSTrackingArea in a view to receive mouseMoved events.
The cursor location in the mouseMoved and mouseDragged events have non-integer 
coordinates (as expected).
e.g. x:140.601562 y:128.082031

However, the mouseDown and mouseUp events always produce truncated coordinates.
e.g. x:140.000000 y:128.000000

This causes inaccuracy with hit testing between mouseMoved and mouseDown.

All the mouse events use the same code to convert the point for the view :

    NSPoint location = [self convertPoint:[theEvent locationInWindow] 
                                 fromView:nil];

Logged as e.g.

    NSLog(@"moved x:%f y:%f", location.x, location.y);

What is the correct way to obtain coordinates that are consistent across all 
the mouse events ?
Thanks.
