Quote - and the mac? If it was rewritten like that kawecki - would it work on mac still???

This depend on how is planed the software. A well planed software can work in Windows, Mac and Linux. Poser has versions for PC and Mac, but not Linux. PovRay works anywhere. In a well planed software most part of the the software doesn't depend on the operational system and remains the same in any version. What only changes is the window management part that needs to be adapted to Windows or Mac or Linux.

Stupidity also evolves!
