As per subject line. This is a shonky restriction that just isn't necessary when every other windows applications works fine at difference scales.
I run 2K monitors at 2560x1440 and text is far too small at 100% so I use the recommended scale of 125% but myDesigner ends looking like a Windows 3 application!
The ultimate goal is for myDesigner to run on the myServer controller and not require Windows at all. This is a very significant project and one that gets needled away with each opportunity.
