Thanks!

Hi Eugen -

I’m seeing this in Rhino 8 here:

Ok…
It’s broken here. This little arrow is missing. Nothing happens when I hover over the ‘thumbnails’ menu entry (submenu should pop out). Clicking does nothing, too.

SystemInfo?

Thanks.
Is Rhino on the main or on the secondary monitor and does it make a difference if it’s the other way around? What happens when you disconnect the secondary monitor?

R8 was running on monitor 1. Tried on 2 - same problem.
Disconnected monitor 2, tried again, same.
