I am currently working through asset updating and wondering why this is happening.
Scenario: I've selected more than 50 of the same feature class poly-lines. Now I edit to add photo numbers from an adjacent photo table window to the poly line feature class. I get through anywhere from 1-5 of these photo numbers entered before ArcMap deselects my features.
Then I have to re-select all of my polylines and scroll to where I left off. ArcMap 10.5.1 has not been this time consuming until now.
Is this software or hardware related?
