I recently upgraded to ArcGIS 10.4.for Desktop.
I am trying to use Map Topology (note: not geodatabase topology) to edit the shared boundaries in a polygon shapefile. When selecting the shared boundaries, the magenta line highlighting the shared boundary does not follow the polygon boundary but appears to be a generalization of it (see image attached).
This problem must be related to a setting in ArcMap since viewing the same data on a colleague's PC works as expected. i.e. the magenta line follows the polygon boundary line perfectly.
Do you perhaps know what the problem/setting is please?
