I am sorry you are running into this problem. To best assist you with drag & drop test automation problems we could use direct access to your application. That way we can see and study the problem first hand and then provide you with the right solution. Without this we can only guess what the problem is and suggest possible solutions to that problem. Is there anyway we can directly access your application you are testing? If needed, you should be able to open a private support ticket (which only and and us in tech support can see) to give us connection details instead of providing them in this public forum.
