Rhino 6 always on top (in collaboration with PlugIns)


since yesterday we are working with Rhino 6 and Vray Next.

We are struggling with an annoying problem. When the VFB for example is open, it is not possible to place it on front of the main Rhino Window. (we are forced to place is next to Rhino or on a second screen, if we want to see it). When its initially visible, it disappears, while clicking on it. Clicking then into the Rhino view, the VFB is visible again, but only if you don’t touch it.
First I thought it is a Vray Problem. But the same happens with Grasshopper. It seems to be an overall Rhino problem.

Is there any option to forbid Rhino to be always in front?

There is also a strange behavior in the options menu. Randomly, it also disappears while clicking any chapter in the drop down menu. Same with the Material Window.

Thanks for reply.

Hi - could you please run the Rhino SystemInfo command and post the result here?

I also asked the Chaosgroup Support. They are aware of this problem. It is probably a Win7, 8.1 issue.

Thanks for confirming that!
