Windows coordinate system different in US and European versions (?)

vonveska

Hi,
I have an application (2D editor) compliled on Vista (US version) using Borland compiler. If I use the default map mode (MM_TEXT) the application works on all versions of Windows OK. If I use some other map mode (MM_HIMETRIC) the application works on US Windows only. On German, Czech and other European versions the graphics are not visible. I read somewhere that the European Windows have opposite axis orientation if using other than default map mode.
Could you please help me to resolve this problem to make the application portable on all versions of Windows.
Thank you for your time and help.
