When the Windows system has scaling set to >= 150% then Windows is in
high-dpi mode. LiveCode 6.5.2 does not support this mode which is why you
see what you are seeing. LiveCode 6.6 does support high-dpi on the desktop
and should behave properly. 6.6 has some other issues with high-dpi (e.g.
text rendering and tooltips), however, and can't be used just yet. Watch
for the next 6.6.2 update and try that out.
