I just tried rolling back to Beta-15, and the issue persists. Beta-15 was displaying just fine before I installed the RC.
It seems Ii have no control over the settings windows. They are just too large and will not dock and/or resize.
UPDATE: I just tried switching the Windows display mode to “Duplicate these displays” and MillMage displays properly. Apparently if the display is “extended”, MillMage tries to use it all. My displays are set above and below. Now wondering what will happen if they are side-by-side…
Apparently not. Using the screen dimensions and the pixel count, the monitor is about 110 DPI and the laptop is 142 DPI. That is actually backwards from what I expected.
