i think what you guys are speaking of is similar to what i posted here.

i can zoom to selected, target, window or anything really and that does not fix the problem. it resets the view but does not seem to reset the origin. its as though after i do a zoom to target i am already 3/4 of the way into my zoom travel. in any case i have not been able to use windows for mac for a couple few months. its completely unusable since i can barely move. there was an update since i posted that last issue above but it was not fixed. i currently have to use the windows version which does not do this. hopefully one of these days it will get fixed.
