I’m having an issue with Rhino 8’s interface. My left sidebar disappeared, so I reset the UI to default and reassigned my middle mouse button to a custom popup menu. That part works, but I’d like the popup menu to stay in a rectangular aspect ratio — instead, it always reverts back to a square.
I’ve attached images to show what I mean. If anyone knows how to fix this or set the popup to remember its shape, I’d be very grateful for your advice.
