Hi,

Thanks! Your icon scalings and other changes work well across the displays. (Of course, icons are not as sharp on UHD as one might wish, but this is a minor issue.) Drop lists and some other items still have rather small arrow heads compared to the button size. Also, the check marks in front of menu items are perhaps slightly small. On secondary display there is an overall fuzzyness issue, but more on that can be found below.

- Then the actual StdFontSize would be calculated based on the above and the TopWindow hosting display reported DPI from received WM_DPICHANGED messages
