Curious. I logged onto free just to check function as there have been a few posts about failure to launch since the new ID went into place. Everything opened just fine for me, but once inside the modeling space my mouse wheel no longer zooms in and out, now it spins the whole model, never did this before. Was this a navigation option I missed in the latest online push? Did I suddenly acquire a spacemouse that I didn’t know about?
You have it in Touchpad mode.
Note the finger icon bottom left corner.
Of course, completely forgot it existed. Solved.
