TranslateScreenPoint returns wrong values on Win 10 1607

After debugging and testing with different Monitor/DPI constellations:
It seems, that this is not a problem of PdxChange-Viewer TranslateScreenPoint.
Windows 10 delivers in some cases/constellations negative ScreenPoint-positions. This wasn't expected by me and leads to an error. I can change my code to get around the problem.

Sorry and greetings

Hello,

after upgrading to windows 10 Update 1607 the function TranslateScreenPoint seems to return wrong values.

Before upgrading, the function returns a correct value on screen dpi setting 100 and 200 (Windows option for text-scaling on hight-DPI monitors). The translated point matches with the pdf-page shown.

After upgrading to Windows 10 Update 1607, the function only returns a correct value on dpi setting 100.
On screen dpi setting 200 TranslateScreenPoint delivers a wrong value. The origin of the point is shifted to the right and to the bottom.

I've verified this on other systems without and with Windows 10 1607 Upgrade.

Is this a known problem?
Can I use an alternative function to get a correct pagepoint from screenpoint?

Greetings
Hans-Peter
