View somehow broken

Hey,

I am using Rhino for Windows in a Windows 10 installation within Parallels desktop on a Mac.
Until I last closed it everything worked fine, but when I opened it today all viewports are black

With a little bit of trial and error I can get it to change


but still not the way it’s supposed to.

I can zoom rotate and so on but the view doesn’t change (numbers do) and if i draw something I can see it works from the command line but nothing shows.

Any ideas? Can’t remember anything changed since I last used Rhino earlier this week. (Maybe a Rhino update?!)

Related to this?

Thanks for the link! Just tried it and it is working again! Thanks for the fast help!
