Which is exactly why it felt wrong...
Fortunately, there is no GUI and we are well on the way with redesign.
It is basically a DLL, so I got off on the wrong foot, so to speak.

typedef struct TheData { unsigned int ID; int size; HGLOBAL hTheData; HGLOBAL hTheHeader; HGLOBAL hTheGains; } TheData;
HGLOBAL is a windows specific data type. No code that uses such data types (HGLOBAL, HWND, can be ported to OSX (or Linux or other operating systems) without considerable change.
In Windows style operating systems, everything is a window so there needs to be something that ties the internal Windows data structure to the objects in your code. This is the HWND (and its relatives like HGLOBAL) data type (which is actually just a long unsigned integer). So if your code uses these, it is intrinsically tied to running on Windows and such modules need to be completely redesigned to achieve similar functionality.
