I have the same issue as Navigation working in Object mode but not Edit mode? except I'm on Mac with external mouse.
Everything is great in object view, and I manually put in shift/left mouse for moving the view/rotating custom, but when entering edit mode these commands don't work anymore.
I tried changing to right selection and 3 emulate, but this results in nothing able to be moved/selected.
What can I do to have my rotate/move commands work the same in edit mode as object?
