Rhino 8 acts weird with popout toolbars

I have this popout toolbar on my mouse middle click.

Before it wasn’t a problem to have the toolbar popout as icons, while the docked toolbars where as cascading menus.
Now, if I set the toolbar appearance to “Cascade as menu” it appears to be one or the other for all toolbars I guess.
Previously the popout toolbar was following its own settings.

The bigger problem is that - now when holding middle-click the toolbar pops-out as a cascading menu, but it shuts-down immediately.

Also, another bug - Rhino, always resets the Middle Mouse setting, from “Popup toolbar” to “Run this Macro”, and with each open file I need to go in the options and re-set it.
