I use the alt (option) drag to duplicate items all the time. I just made the switch over to InDesign CC from CS6, and now it doesn't work. The odd thing though is when I hold down alt and hover over an object, my cursor does change to the double arrow, as if the duplicate function is going to work. But when I go to drag (obv. while holding down on alt), and let go, the object simply moves with no duplication occurring.
Has anyone else experienced this? Any ideas on how to fix this?
