I'm encountering the same issue when using the LOCK interaction mode. When I hover over the VS click spot and scroll the mouse wheel, it zooms the view in or out instead of adjusting the VS setting. Switching to the LEGACY interaction system does resolve the problem. However, since I use LOCK by default, it's not very convenient to constantly switch to LEGACY just for the Arrow. It would be great if this inconvenience could be addressed somehow. Everything else is fantastic - an outstanding product, thank you for it.
