Running ‘_PopupMenu’ works in 8 i have on an alias, to show the most recent commands. In rhino 9 i have never had it appear once. It doesnt work when running it manually either btw. ‘PopupMenu’ no errors, just doesnt appear.
by holding down the middle mouse button for a while and getting the little menu, then letting go the menu does pop up.
In the options->mouse menu ticking off ‘manipulate view’ ofc makes that menu appear instantly, but it does not appear when calling the command(which is the way i use it).
