I am curious why AutoCAD 2020 indicates a drawing is unsaved, or changed, or modified through the indicator of an asterisk (*) after the file name, when switching between different open files in the same instance of AutoCAD. If I modify a drawing, or move the view on a layout, I expect that the drawing will report itself as modified, and unsaved.
So why does it also report the drawing as changed, when I haven't modified anything, or changed the view. This strange behavior happens every time I change between open drawings. I am not referring to the tabs at the bottom of the program, including Model Space and any Paper Space layouts. I am only referring to the tabs at the top of the program, indicating different open files (eg. DWG1.dwg, DWG2.dwg, etc).
Does the act of looking at a file modify it? I would rather not have the software telling me there are unsaved changes when all I am doing is tabbing through my open drawings. Sometimes, basic mouse movements will pull down a drawer when mousing over the tabs, which shows us a visual preview of Model Space, and Paper Spaces. Even this brief, often accidental action, changes the files to be designated as unsaved. This behavior makes it impossible to trust whether something is saved, and encourages saving the file every time you look at a different drawing, even if nothing is changed.
Why does it do this?
How can I change it?
