Where or how does Wine use the "documents and settings" folder? Is that configurable in Wine? I think Winamp can't see that folder. That's causing the Media Library not to display. The media library location is not configurable in Winamp..
The locations are configurable in Windows, good applications use shell functions to locate places like that for this reason, eg GetUserProfileDirectory and the more general SHGetFolderPath. You should look at the output of some debug channels to find out if it really can't locate this path, instead of guessing.
