Using DraftSight 2019 standard licensed product on a newly built Dell Precision M3800 Windows 10 machine. It has previously (before being rebuilt) run Draftsight 2018 without issue.

Ever since the machine was rebuilt with DS 2019 put on, it allows you to work normally until you draw a polyline or a rectangle, at which point, the graphics area completely freezes. The menus etc all continue to work. REBUILD command doesn't do anything to bring it back. The only way I've found to get it back is to close and reopen.

Clearly this renders the product completely useless.
