I often have to open many drawings just to quickly look, then close them.  If I zoom in or out, AC considers it a 'change' and prompts the 'do you want to save changes' box.  This is painful when trying to open/close many files in a few seconds....Is there a way to turn off this prompt if no actual changes have been made?  Autocad 2004.Thanks,Mark

Use a viewer instead of AutoCAD if all you are doing is looking.
