Hi there, I have a 2.2Ghz MBP. When i go to preferences to set the trackpad and enable dragging (e.g. double-tap to drag window without releasing finger, release to stop dragging), it behaves the same as drag lock (double tap to lock and drag, tap again to release). Is anyone else experiencing this? Tried on window and slider bars and still the same. Thanks for any help. Edit; I'm running 10.5.2 and the drag lock box is not checked.
