Apple Magic Mouse oddities

[tkbd]

Hi,eddieh,
I tried to verify each operation with Magicmouse,and I got the same result as you explained.
I also couldn't use the camera except for one button mode.
(In MacOS Big-Sur , Wings3D v2.2.9 and MagicMouse(Bluetooth))
(But I always use 3-button mouse)

So...I found that one of solution for Middle button problem with MagicMouse.
It is the open source software that called "MiddleClick".
This software Emulate a scroll wheel click with three finger Click or Tap on MacBook trackpad and Magic Mouse
with macOS Big Sur11.5 support. But I don't know it support Catalina....

The Binary version can download from a following URL
https://github.com/artginzburg/MiddleCli...es/tag/2.5

How to install and setting
1. Download MiddleClick.zip and get MiddleClick.app

2. Change Privacy preferences on MacOS System before use the software.
Privacy preferences > Accessibility >Security and Privacy
Check checkbox of "MiddleClick.app" from the app list.

3. Run MiddleClick.app ,and icon appear in top menu bar.
4. Click the top menu bar icon of MiddleClick.app
5. You can button setting which triple tap triple click for MiddleClick.

What is TripleClick/tap?
It working as Middle mouse button click.
It is a feeling of pressing all the buttons on the left, right, and center of the mouse in same time.
Using tap or click with your index, middle and ring fingers on MagicMouse.

I recommend setting is triple CLICK MODE (The setting can change from top menu bar icon).

My Wings3D 2.2.9 Mouse Setting is "3 buttons" and "Wings3D"
I check it work fine with Wings3D.
It may take some time to get used to it.

I hope it helps you.
