Wine seems to be ok at running things I have written in Visual C++, even when fairly complex grapnics are used. There used to be a problem in the number formatting routines in the wine built-in msvcrt.dll, which was fixed by using the Microsoft version. I have seen this same problem, and solution, in some commercial software. Foolstroupe is right, the only way to deal with wine is to keep at it until you are happy.
