Ok, I cannot replicate the problem, however, the only event out of the ordinary was to bring into the drawing, an AUTOCAD "External Reference" .dwg
In one instance, I exit AC and calledforanew drawing,using the latest settings. The windows worked but the doors, any door, produced this Warning Message -" Pen number is less than 1 or greater than 255 at line 447 in the 2D script of the file ws_wallhole_us_10.gsm"
The file is corrupted and was abandoned. I spent more time trying to figure the problem than actually starting new again.
Thanks, Lynk. T'was good to hear from you again.
