This really has me baffeled !
Autocad 2015 64bit
Win 7 64bit AMD firepro 3900
This particular file ONLY !
When drawing a polyline I do not "See" the line as I pull away I do see + as start point.
I can end the command and see the line, so I'm not on a frozen layer.
If I draw a "Line" I DO see the line as I pull away
See if anyone can confirm this on the attached drawing.
