Pop up menus (print, layer manager) have disappeared. When I click layer manager, some controls are grayed out and I cannot click on the drawing as if the layer manager is open. It's nowhere to be found however and I cannot figure out how to re-enable (nor how this happened in the first place). I've tried disconnecting my external monitor, have started / restarted DraftSight and windows multiple times, and I uninstalled / reinstalled draft sight. The issue persists. What else can be suggested?
