Well, you've given me a chance to vent - which I'll take, since trying to express anything to Microsoft is futile. Office 365 is one of the worst ideas I have ever seen. I still can't decide if it is software, cloud-based, client-based, or simply a pricing scheme. I suspect the last of these, since when you use it, it opens Excel 2019. So, I think Office 365 is a pricing overlay of other Office products. And, it remains unclear to me the extent to which it is cloud-based. I really hate Office 365, and the fact that it was not designed with Windows 7 in mind does not make me any fonder.
I sense from your comment that I should just get modern and go along with what Microsoft wants me to do. Well, from all indications, Microsoft wants me to connect them with everything I do - my wife's machine with Windows 10 is a constant frustration, as meaningless messages constantly bombard her - all designed to have Microsoft take over her thinking for her. And they usually get it wrong.
So, yes, I'll complain about Windows 10 and many other Microsoft products (don't get me started on Teams). And, I would have preferred if JMP continued to support Windows 7. It was nice that they did that with JMP 15, and I am simply expressing my disappointment that they did not continue to do so. I realize it costs them time and money to stay compatible with other software (note that JMP is not compatible with Stata, so they do make choices about what to be compatible with).
