Sorry for the miss-understanding - what I meant is: when I move the mouse pointer from i.e the Top view to the 3D view, then the "Area/Zoom/Pan/Rotate/Reset" buttons in the 3D view automatically show up without the need to do a click (and the buttons disappear in the Top view as expected). That works very reliable from any view to any view - I always assumed it's meant to work like that :-)

When the mouse pointer is moved outside any of the views, then the buttons do not show up in any of the views (kinda expected). When I enter a view from outside the MoI window, then the buttons show up in that specific view (as expected). For me, this does not require a mouse click. That why I thought this mechanism might be suitable to determine which view has the focus for the mouse-wheel zoom.

Feedback is highly appreciated!

TIA and best regards

Bernhard
