A weird behaviour is happening when I switch from model to layout : if I use the layout panel, everything works fine, but if I use the tab in the views tab, a new panel is consistently reappearing, which is a bit annoying.
A video to illustrate this :
Hi Felix -
I can’t reproduce that behavior here. Could you export your window layout and post that .rhw file here?

Hi Wim, I thought you’d ask that. It seems like this behaviour comes from a duplicated Layers container. I have to admit here I have no idea what I did back then with this window layout, and how I ended up with this container (definitely not created on purpose) 
But no matter that, I already have a Layout panel opened, Rhino shouldn’t force me to open another one.
Anyway, here is the .rhw file : 2023-09-28-Window Layout.rhw (82.6 KB)
