I have a problem with ArcGis 10.1 which I rarely use.
In an edit session I select a polygon. I would like to 'Create Layer for Selected Features' and can do this; the new layer appears in the table of contents. When I try and move the new layer, the old layer moves with it.
When I click on the polygon the option of selecting the two coincident polygons appears but I can't get these to separate. It seems to be impossible to do anything to one feature and not the other.
The strange thing is that yesterday the program wasn't behaving like this.
Can anyone can explain what is going on?
