Dynamic file extension mapping

Seemage’s behavior is such that smg, smgGeom, smgXml and smgProj file extensions are mapped with last executable that was used (Viz, Mockup, Publisher). You can force one program (i.e. VIZ) to map with a given extension (.smg) using right-click/open with >> always use. This will overload Seemage's mechanism. To come back to the Seemage's dynamic map, go to Windows Explorer, menu Folder option/File Types and use the Restore key.
