Holy cow @DJ! It's worked!! The issue of the workspace sliding up under the menu bar seems to be gone. What a relief! 

Thanks so much for fixing this and the work you put into it. 

I also love the extra virtual desktops. I've been thinking of asking you for this for a long time now. Your like Apple, anticipating and implementing what the customer wants before they even ask!  

One question about removing an unwanted desktop; When I choose "Remove" will I get a warning if there are controls on it? I can see myself accidentally erasing a whole page of controls without this protection. 

Again, super job! I'm thrilled and can't wait to get started organizing my project.

:) you’ll get a warning. Won’t be removing any desktops with stuff on it

and thank you for the kind words. That’s nice to hear!
