Gadzooks, thank you for your comment; the to-and-fro was temporary, while moving my office and traveling. Per Jim Smith's good answer, I have now upgraded to 2017 on all my devices. And sorry about the misleading current subject of post. I am not very familiar with using the knowledge base and was trying to ask a new question, but inadvertently changed the subject of the old. I'll try to change it back now, because as you mention, it would be nice for others to find the response. And I have since gotten a response from VW about the green line around viewport question which I will try to implement today.
