I believe I have stumbled upon a bug here in the multiple view pane configuration.
While navigating the lower right viewport with the 'walkthrough' tool, i encountered the bug when attempting to initiate fly-around.
My typical workflow is using the navigation keys (W, A, S, D) and elevation keys (Z, C) to orient my camera. Then I will click with my mouse to engage flyover, to reorientate my view, and repeat the process of using the navigation keys and elevation keys until i've achieved the position i want.
In the current software, when I initiate the flyover tool the following occurs.
[Mouse Right] - (Right) viewport rotates clockwise
[Mouse Left] - (Top/Plan) Rotates Clockwise
No Flyover occurs in the lower right viewport, where it is the selected, and intended viewport for rotating.
Thoughts?
