Hi,
if an AutoCAD file is opend (doesn't matter, if ACAD vanilla, Mechanical, Architecture or whatever) and the user is JUST LOOKING - means the user is zooming and paning around, maybe selecting something to explain his idea to others - by simple zooming and paning the DWG will be saved, the DWG has a dirtyflag (small asterix at filename)!!!!
With data management this is a bad behaviour, especially with Factory Design Suite this is a silly and totally worse behaviour.
