vdws: I wouldnt recommend touching the HexagonGrid option. Im not really sure what it is for, but if you set it FALSE your start menu wont work anymore. Well, it will, but after a long pause while it changes back to the default WM6.5 grid. You would then need to change the registry value mentioned in post 1.
