Hello,
I'm having this issue where the window that contain the materials, environments, etc extends beyond the screen. So I can't switch tabs or close, move or minimize the window. I know its probably a simple solution, but I just started using Keyshot6 on macOS Sierra.
Thank you in advance for your help!
In the menu bar, click on Window > Dock Windows. And then upgrade to the latest version - KeyShot 6.3.
