Sitebuilder Woes

Is there anyway I can use the old sitebuilder plus on windows 10? I've been with you guys for years, but this new sitebuilder is TERRIBLE! At least with the old version pretty much everything was on the window at one time. With this new one I can't have more than one of my pages open at a time. I frequently have to update multiple pages with the same content, but now I have to go through this ridiculous process of copy, twiddle my thumbs while my next intended page loads, and then paste. All the page setting options are also gone unless I go through a dizzying array of drop down menus. It may look a lot more snazzy than the old version, but functionality wise it's a total fail.
