It is odd, I've sent you a link to the site in a private message.

 

The site is hosting a DNN site.  We have other ajax components that work fine and no other outstanding problems so its very odd that the component won't work.  Hopefully when you see its behaviour for yourself you might get some inspiration! :)

 

You'll have to upload a relatively large file to clearly see the problem I'm working with a ~25mb file.
