Horizontal/vertical constraint not working
Seemingly overnight, I lost the ability to constrain movement of objects to horizontal/vertical/45 degrees by holding down shift key. I can't find anywhere where I may have inadvertently turned this function off. Similarly, I can't duplicate objects by holding down option+command. It feels like a bug. I've tried quitting and restarting.
I should say I'm on version 12.1.0.56 (2017) on an iMac running Yosemite. I haven't upgraded to High Sierra for fear of some software conflicts. I believe this is preventing me from getting latest update of InDesign.
Anybody experience this before?
