Just upgraded to Carlson Survey OEM 2018 & it is running pretty smoothly.
I am getting some sort of a visual 'trailer' when I draw a line as I move the mouse along.
Have not seen this effect before and the many lines apparently drawn while I am picking the node, for instance, will disappear after the line is drawn.
I thought it my be something similar to a Maxsort setting but wondered if I am the only one.
