I rage quit using the program yesterday and Had a good sleep. here's the problem I found:
I was following this tutorial https://youtu.be/pgWWVcM5YJY to improve a Covid Face shield file. I couldn't use the paint select tool as shown at 11:55. it just would not select anything.
I'm a fairly keyboard heavy programmer, so I use Alt+Tab a lot.
It turns out Fusion 360 does not recognize that the Alt key was released. It gets stuck in component drag mode. When I go back to fusion I have to press and release the Alt button again before I can do just about anything in the program. I am guessing the same issue would happen if I was holding the Shift key and switched windows.
Windows 10 V1909
Fusion 360 2.0.7824
