I am having several issues with 2018:
Getting save errors “This document’s file has been changed by another application since you opened or saved it.” - I normally save to dropbox, but it does it even saving locally - also deleted all extensions.
Layout Selection - Something has changed when clicking on a drawn object in Layout. I used to be able to drag an item easier, now it seems to want to rotate or scale the object - the threshold for moving is smaller than before?
Anyone else experiencing this?
