I have checked and installed the latest version of Java 7, update 45. Does not solve the issue for me yet.
Since the form is appearing the issue is something to do with the client machine where you are opening the form from.
Try again after clearing the web browser cache and java cache. Also you may try this from another machine and confirm of the situation.
I am trying this on my laptop. I cleared web browser cache and java cache, but this repeats itself.
