I have been doing detailed editing of river courses and saved periodically using Ctrl-S. I have only realized now that this did not save my edits (just the project) because the option to save edits was not checked by default (I have now checked it). When I exited, a number of save screens appeared and I only clicked the first one because I thought the others might be saving over the real data. Unfortunately, I have lost all of the day's edits. I find it difficult to believe that the default is to not save edits when Ctrl-S is pressed. I don't suppose there is a way of recovering my lost work? I am using version 3 (recently installed). Needless to say, I am a newby, learning through hard knocks. I have also now realized that I should not be saving to OneDrive.
