I have managed to implement a fix for Swiftpage ACT! that overcomes scaling problems on my Surface Pro 4 and Surface Pro 2 with Windows 10 Pro. I can run it at full resolution and with 200 and 150 scaling respectively.
It involves making changes to the MANIFEST area of the exe file that informs Windows 10 that the program does not scale.
It worked with DOPUS 11.17 64bit but the internal checks recognised the change and stopped the program.
The code in MANIFEST area that made the difference:
false(changed from "true").
I am aware that there is work under way to help with this problem in DOPUS but offer it in the hope that may help.
