I’m trying to move ahead with a project and I have found the program stuck. No curser. Mouse arrow moves. Unable to escape. Cannot save or start new command. The last command joined to objects and created a closed polysurface that is a bad object. The resulting object is not longer highlighted in yellow. Is there some way to disengage the program without losing data? The command line is asking me to select objects to join. It seems to keep repeating the command but not let me respond. I’m using V7.
