... not only mouse (or pointer) and zoom but also a pan is extremely! slow, with delays and sticky (especially with some more drawing material). As you pan with mouse, the content of drawing delays of some microseconds! Also snap is slow and not precise. It is not possible to work with this version of AutoCAD for MAC professionaly at all!! After one day I returned back to Windows version! Waiting for some improvements or any help from AutoCAD helpdesk!! Thanks, ...
