Well it's now 9 months after the last posting. HX Edit does not behave properly with Windows 10 high DPI scaling. On my 4k monitor and 1080p main screen (both with scaling set to 150%), HX Edit is blurry. If go to the properties for HX Edit -> Compatibilty-> Change High DPI Settings and check the "Override high DPI..." box, and select "Application" from the dropdown, the blurriness goes away. However, the text is really small since it's not being scaled.
Anyone know if they are going to add proper scaling in a future release?
