Maybe it's time for me to suggest 3dconnexion add TBC full features to their app list. I use the Space Mouse Compact all the time in 2D. However it does nothing in 3D view. I use Bricscad and it's fully functional there.
Do you have issues with a wireless mouse occasionally not working? Three years ago I was using a wireless Logitech set of keyboard and mouse. I've never developed the skill of running a 10-key number pad without looking at the keys. I'd be trying to enter a bunch of numbers into a spreadsheet and when I looked up it had lost connection for a time and I'd have to fix it. Or I'd be zooming in and out with the mouse and it would just get hung up and forget what it was supposed to be doing for a while. I got a wired mouse and keyboard, problem solved!
Also I'm amazed you guys can make use of all the extra buttons on a mouse. I find it awkward just trying to get my thumb on the side back button. I can get the front side button since that's where my thumb is anyway. The other one requires rolling my hand back and I loose control of the mouse.
