------- Additional Comments From fairy_maiden1999@yahoo.com 2006-24-02 04:13 ------- Mapsource crashes hard whenever serial communications are attempted. If setupapi.dll is copied into system32 and winecfg is used to set it to "native", Mapsource is then able to handle the crash and shut down gracefully (as opposed to wine segfaulting). This serial communications bug is the only thing keeping Mapsource from gold status.
