Drag object does not snap in
I build a course with a drag and drop interaction with three drag objects and three drop targets. One drag object is always connected to one drop target. The drag objects snap in on each drop objects, no matter if it's correct or not. The solution is presented in a solution layer. This all worked fine until I installed update 5 on my pc. Now one of the drag objects doesn't snap in none of the drop objects. I did not make any changes in the interaction. Has anybody an explanation why one drag object behaves different?
