How do I delete the Portrait Views in Captivate 9?

Making a regular, blank project instead of a responsive one is probably the easiest solution. But if you've already gone down the responsive road you could remove the media queries in the project's CSS file after you've published it. The Cap project file would likely still give you the tablet and mobile options in the editor though, and if you republished the file you'd have to remove the media queries again.
