Sometimes, randomly while I am drawing, my middle mouse button will start selecting, basically, mimicking the left click, instead of panning or allowing shortcuts to rotate.
The issue is has happened on multiple mice, and my middle click works in the sidebar to fast scroll through a list of folders. The issue is also persistent across different fusion files, any I open has the same issue until I fix it. I can remedy it by selecting the entire model, and then pressing the select icon under the Tools tab, or by restarting fusion. I don't know why the select fix works, but it fixed it every time I remembered to try it.
I have a screencast of it and you can see that I am indeed middle-clicking when it is selecting. Sorry, it looks a bit frantic, I wanted to get a video before it went away.
