Thanks to both of you for your replies.

Mouse = Bluetooth Evoluent Vertical Mouse 4

OS X 10.12.2 on MacBook Pro Retina, Early 2015.

Based on Maxim's comment I will try a USB Mouse and report back.  It will not be until tomorrow.

At this point, the click issue has a great effect on speed. Coupled with the inability to customize the tool panels in the Drawing Tools (except for turning things off and on), I have to say AutoDesk still has work to do on this version.
