I have a user running PowerSurvey V81 Ss2 - latest version I believe and when his supervisor tries to review his file in V8.5, the temporary graphics are still displayed. I thought this was fixed a few versions ago.
I am also seeing these persisting if a file is saved to DWG. I believe I had even turned off the display of temporary graphics prior to saving the file. As we move forward, with InRoads no longer supporting AutoCAD, things like this need to be fixed and remain fixed.
