Stretch>Select>Shift-Click>Deselect is not working. 

It was working with previous versions of both and now it is not. What has changed? I've tried changing system varibles; OSOPTIONS, SELECTIONCYCLING,... 

It's enough getting used to new Magic Mouse 2 with ACAD (not having 3-button mouse), but now this?

Please help. And do not tell me to post to AutoCAD LT for MAC forum. There isn't one. I've clicked on those links and they lead me in circles to ACAD for MAC/General Discussions forums.

System:

AutoCAD LT MAC 2015 (J.51.M.453)

iMac17,1 27-inch 5K Retina Display Late 2015

OS X 10.11.1 El Capitan
