Phrostie: Well, after much testing & tweaking, I've finally come to an impasse. All the hangs are very repeatable and "fatal" to continuing in that session. I'm not running the latest wine version but those that are have been experiencing the same issues. Without further facilitation or help from the ITC, CADopia or Codeweavers, I'm afraid that IntelliCAD will continue to be unuseable on this platform. This is disappointing because it is soooo close to actually being useful. I'm going to stop further testing until their are advances to make this work by either the ITC or Codeweavers. Thanks for all your help to date.
