I have a Surface Pro 7 with a high-DPI display and W10 display scaling set to the default 200%.
Many, many UI elements in ProArchitect 15 remain designed for 2010-ish low-DPI displays. I can cope with a lot of it, honestly. But the Help engine–which I need a LOT as an intermittent user!–is very nearly unusable. Not much help.
Please fix the Help system for high-DPI displays. But soon after, fix all the myriad other UI bits and pieces that remain Windows 10-scaling-unaware.
