I think you're losing sight of the issue. The issue is how to view, at 100% zoom, a single page, rather than multiple pages or documents side by side. We all know how to change the zoom - that is not the issue. Prior to our "work-around", it has not been previously discovered how to have a single document at 100% zoom on a widescreen monitor. How it's achieved or what the prior zoom is or was is not the issue - the target here is how to get a single document wide at 100% and our solution works.
