I tired this many a times now. I add icons to the popup toolbar, say it as popup1 group, and then assign the “default popup 1” to the mouse middle button in options.
in the same session, I close the popup tool bar and open it again,and it works fine, so I am a happy man!
I close Rhino or Rhino crashes because of t-splines, and I am to create the popup tool bar again…
“Default Popup1” does not even show as a toolbar option now when I open rhino again.
Thanks in advance.
