Using the easeljs tutorial here I created a drag and drop "test" in Animate CC using symbols and "pressmove", "pressup". It works fine in all the browsers (and Ipad) except for Safari on my mac. When starting to move the "draggers" they "jump" to a different location. They also move closer and further from the mouse when dragging.
The test page is located here:
Any help would be greatly appreciated. Thanks!
