I'm having the same problem, bugs me so much I check for an update every
time I open AC. Please please get the fix out asap. It is painful to use
the magic mouse with AC20 & OS Sierra. This is a bug that affects almost
every move & click in ArchiCAD....
Over 11 years later and you guys just made my life sooooo much easier.
Someone should make this into a tutorial video. Editing meshes have been
the bane of my Archicad work. But I think you guys just changed that!!
