Thanks Justin. I don't think that's the problem since any other icon I select the same way drops. I just went back to double check and found a couple of monsters I know for sure I don't have on any of my maps and are not associated, and they dropped on the map just fine. Kind of weird. Also,I just tried it using Firefix to see if it's a browser issue, and no, I could not drag and drop the Adult Green Dragon there either.
