Rhino window deactivating



Hi everyone!
I’m currently working in a worksession with more than 10 files. It often happens that, while a command is active (quite a lot of them, not one or some in particular) the Rhino window will flicker or deactivate, so keyboard commands won’t work and I have to click in the window to make it active again. But even after clicking the window will often deactivate again.
I’ve searched the forum and found nothing. Any ideas what it could be?

Hi Pietro - Is this in Rhino V6? Can you please run the SystemInfo command and paste the results here?




No, it happens in v5, don’t know if it happens in v6 too since I didn’t use it extensively yet. Anyway, I guess you were referring to the v6 command since there is no such command on v5! Here are the results:

Hi Pietro - I do not have an idea -

Can you tell me exactly what you mean - what is it that fails to respond, the command line, or interaction with Rhino’s viewport, and what exactly do you do to get it back again?

(btw, I changed the category to Rhino for Windows; Serengeti is for reporting problems etc with the ‘WIP’ version of Rhino, currently V7)



Well, it’s quite unpredictable so it’s not easy to get a screen capture of it. Let’s say that I am tracing a polyline (but that’s just an example) by inputting lengths via keyboard. It will sometimes happen that I cannot input them anymore or that I cannot confirm the one I inputted as the Rhino window is no more active, thus not responding to keyboard inputs as if I switched to another window (like when using alt+tab to switch windows).
To make it active again I have to click somewhere inside it with the mouse or use alt+tab from the keyboard. Nevertheless, it will sometimes keep deactivating right after I have clicked on it.

Hope I was clearer!

Oh yeah, sorry about that!

Hi Pietro - thanks - I do not have a good idea yet - what is the PC that you’re running on?
@JohnM, @stevebaer - does either of you have an idea what might cause this? Rhino 5.

The only thing that comes to mind is that a modeless container in Rhino has input focus. For example if you have the object properties panel open and click in it mouse and keyboard input will get set there. You can tell if the Rhino application is still the active application by checking the color of the title bar at the top of the main Rhino window.


The bar colour actually changes when the rhino window deactivates, but
there aren’t any other active rhino windows open! Are you referring to a
floating proprieties window, for example?
