Rhino steals focus when opening new session

Any way to prevent rhino from stealing the focus when new session opens?

Often working on something, open new rhino for whatever, go back to what I was doing while new session loads up

then half way through a complex selection and POP new session is in front and stops work.

Is this desired behavior? Or technically unavoidable? I’d rather it just waited in the background.


Does anyone know if this is resolved in recent builds/versions/betas?
Incredibly annoying and intrusive to workflow when this happens.
It might not even be Rhino’s fault. Does anyone know how to change this Window’s behavior? I’ve only dug into it a little bit.

Hi @pascal, wondering if you have any thoughts/ideas on this?
thank you,

Hi Robert - only that I see it as well, … though I have not actually tested against other programs starting up - I sort of assumed that it was more obtrusive because Rhino is the only program I open and close and uninstall and reinstall seventy times a day.


I wouldn’t say that Rhino is the only program that exhibits this behavior on my end - Photoshop seems to do this to some extent as well - but as Pascal, Rhino is the program I open the most, and it is also the one that takes the longest to load…


Would be great if there was a system option we could tick off in options that made Rhino open in the background without stealing focus.

Hi Robert- just as a test, try opening Rhino from a shortcut that has the /nosplash switch - does that behave any differently?


removes the splash but still brings focus to the new instance.

Just to push this topic again: I experience Rhino regaining focus at least twice during startup. And it’s extremely annoying, especially if you do Rhino plug-in development and have to start it many times a day.
So if there is a way to prevent this behavior, that would be really nice.


Just commenting as a way to add a vote that Rhino stealing focus when opening is extremely annoying.
Part of my workflow is opening several Rhino files at once. Imagine opening 9 instances of Rhino, one after another, each one stealing focus 3 times during its opening process, so you get 27 focus steals interrupting whatever else you are trying to do while waiting for all those Rhino files to open.

It would be extremely helpful if there was a /background flag or something that could force Rhino to open without stealing focus.


I also vote for an option to open Rhino without taking focus on Windows. I manage a team of CADs so I have to open many Rhino files during the day to review them, and waiting for Rhino to open without being able to do anything in the meantime is a sizeable chunk of my workday currently.
