Can't seem to get the "drag and drop" area to accept a file.

I am trying to build a contact form which includes a large area for "drag and drop".  When I drag a picture into the area, the page changes to where the form is no longer available.  How can I make this work?

I havent't uoloaded the contact.html page to the server yet. If I upload to you a screen shot it will be as it appears thru a browser on my computer.

I tested the form at http://www.jotform.us/form/71194063525151 and could not replicate the issue.

Here is the screenshot of what I see at my end.

Please the from again at http://www.jotform.us/form/71194063525151 and let us know if you continue facing the issue.
