@rvk yes, the font become smaller (pls see red box in attached pict )
>> Do you include a manifest.txt in your program/resources?
No, I dont use a manifest
>> Is this a designed form (not created at runtime)? And is it designed on 100% 96dpi (pixelsperinch)?
this is run time pict,
>> Is your developing machine Windows 10? With Delphi 7?
yes , delphi 7 on win 10
as I said before, if I ran the .exe on win xp to win 10 22H2 is normal, not either font size changing or form shrinking.
Please if any other suggestion, I'll try....
Thanks
