to make the pan&zoom hotfix work, updates 1&2 have to be installed in advance, but update 1 cannot be installed using a test version ( in my case, on a late 2010 MacBook Air 13")
question : are updates 1 & 2(the pan&zoom hotfix obviously isn't - according to the sluggish cursor movements) already included in a one month test version, downloaded 10 days ago ?
I just noticed that the pan&zoom issue gets significantly better by turning everthing from ON to OFF in 3dconfig. - probably the best option for Mac test version users, as installation of Updates 1/2/pan&zoom hotfix are not possible, according to my experience (- no valid Autocad version detected)
