Viewport doesn't gain focus by zooming

Here (V5, V6, no V4 to test) moving the mouse cursor over another viewport without clicking does not activate it - but, as soon as I roll the mousewheel, it does activate it, so it zooms in the viewport the mouse cursor is currently in.


Nay! Y’all do not see this?

What up with this discrepancy? V4 does the same thing here.


Nope - this is what I see… Note I did not click in any of the viewports, just rolled the mousewheel.

Mine works like Mitch’s, not Pascals.
Rh5R12, 32bit, normal wheel mouse.

Hmm- I have tried a couple of mices and they both do the same thing. Light touch I guess. Let me see what I can find out- thanks for the feedback, all…

Can you try Rhino in Safe Mode and see if that behavior changes? Thanks.


In Options > View; Pan section, is the option checked for "Auto adjust camera target after Pan and Zoom?


In mine, it is set to ‘autoadjust camera after pan & zoom’

but unchecking that box makes no difference.

Mine works like Mitch’s too, including V4.
Mouse over does not change to that viewport unless a command is running.
Moving the mouse wheel instantly changes focus to the viewport the pointer is over without clicking.

The ONLY exception to this a a floating viewport.
The new floater can be current and I can wheel zoom another viewport without it changing focus.

Scott’s works the right way. I mean, like mine…


I just recently updated to Win10, is that a factor?

Seems to me if I DO something in a window (including zooming), that window should get focus?

Yeah, I honestly do not know what is the designed behavior - I could make a case for each. I’ll see what I can find out.

Ok, back on my other computer and I’ll confirm this: the behavior is different on the SAME version of rhino on different versions of windows. On Win7, it works as I have always experienced it: zooming in a viewport puts the focus on that viewport. In Win10, it does not, which I find problematic. If I can kick in my own preference here, it would be as I always remembered it: zooming in a viewport gives that viewport focus. Thanks…

FYI: Installed Win10 on the other computer and the unliked behavior is now on that machine as well. Definitely a Win10 thing. And definitely drives me bonkers.

OK, thanks, I’ll see if we cannot get this working right for V6 at least.

For anyone else who is going bonkers on this one and finds this thread, following the youtrack trail led me to the fix:

"apparently the behavior on Windows 10 can be turned off.

On Windows 10, left click at bottom left corner, go to Settings->Devices->Mouse & touchpad, and turn off “Scroll inactive windows when I hover over them”. Selection menu wheel scrolling should work like it used to."

Worked for me and restores at least some of my sanity, thanks guys.

That’s true. The Windows 10 change effects Rhino V4, V5 and V6

THANK YOU THANK YOU THANK YOU MARK. This behavior has driven me crazy for a year. That solution works.
