Carlotta thanks for your explanation. Other than DOS programs written a long, long time ago, I can't recall any time I have run into the non-compatibility problem. Now the driver thing, don't get me started. There are already plenty of my rants in my posts here.
Looking at your web site made me smile b/c it kind of reinforces Microsoft's plan for the future. I was referring to in a post here lately that the project really began with the ill-designed Windows 8. Unfortunately that left such a bad taste in users' mouths that they are wary now of any changes to the GUI Microsoft is trying to introduce in Windows.
Anyway welcome to the forum and I am sure you have many things you could share with our community. I look forward to reading your future posts.
