In Rhino 9 Beta SoftTransform remains enabled after closing the SoftTransform panel. Closing the SoftTransform panel should end SoftTransform. (Not just docked.)
Current procedure to end SoftTransform if the penal is closed.
Open the SoftTransform panel using the SoftTransform command.
De-select the “Enable” box de-selected.
Close the panel.
A user may move control points not knowing SoftTransform is still enabled, and does not realize other control points are being moved. This will inevitably lead to a objects having their shape changed in unintended ways, which may not be noticed initially. Not good. Actually very bad.
