Hmm, the interface for CtPII was totally changed and unfortunately SLIC wasn't really updated to reflect this. Here's a list of all Open-functions that exist in SLIC with a description of what they did in CtPI. They all still exist in CtPII but I have no idea what any of these open now, so if you haven't already, try them all. If none of these works, then this would be something to put in a patch, I suppose...VOID OpenCity()
