Since you have the privilege of the source code, can't you just compile it for whatever operating system you want to? Or did you have it call Windows function calls in the source code? It's far better to have a native version for each operating system than to use WINE as your method for making it cross-platform. As a compromise, I think, think, don't know, you can compile it with winelibs or whatever to make Linux version. Cheers, Jake
