I have a Logitech MX1000 that has 8 buttons, I had to uninstall the SetPoint software to allow the middle button pan and zooming with the wheel, so I cannot assign a function to the buttons as the manufacturer would prefer. So how could I set the extra buttons that I have that have no function in my Architectural Desktop session? I would like the forward button to be able to toggle the properties window (Ctrl-1) and the back button to toggle the Design Center window (Ctrl-2). If you check out the images, they are the buttons right above where your thumb would go, mirror the image if you're a lefty! Any help would be greatly appreciated. Thanks.
