Wacom mouse wheel doesn't zoom

Not sure how long this has been going on, I usually use the stylus…

The OS sees the mouse wheel, I can scroll up/down in other apps. But Rhino doesn’t seem to see it. The MMB does bring up the popup menu, just no scrolling zoom. I thought it might be the SpaceMouse driver(s), but I just uninstalled the whole suite and still no Rhino zoom.

Intuos3, Rhino 5 64-Bit for Windows, Win8

I also use an Intuos but don’t have one of their mice to try and reproduce this. It’s this one right? https://www.wacom.com/en-us/store/other/intuos3-mouse

Yep. I’m 99% sure it DID work fairly recently, too.
