The most important limitation that you'll encounter will be that you cannot have any overlap of objects, neither drag sources, nor drop targets. That means that if you have one big drop target, its bounding box has to be totally separate from the bounding boxes of the drag sources.
Do not define correct answers at all. Target object should Accept all. For the snapping behavior change the default to 'Absolute', which means the dragged object will remain where it is. You could add a Clear and a Reset button.
Lilybiri,
I really appreciate all of your help. I am going to check out the absolute suggestion. However, I came up with a plan "B". I knew I had done this once before, but it took a good nights sleep to come back. I thought I would share in case anyone else runs into the same obstacle. I set a tiny little box in a space that no one will drop to as my target. I used the drag and drop interaction to set up my process. I set the words as the drag items and the little box as the drop target. I then went into options and turned off "Send drag source to original position" and turned on "redrag the dropped source". I then drug the drop box and the submit button off of the screen. Now the words can be drug all over the slide and placed anywhere. Hope this helps someone else too.
