Async upload doesn't work in Opera

[James]

If anyone's tried the demo page, you'll get this message in your Opera console if you try it:

Error trying to get server response: ReferenceError: Security error: attempted to read protected variable

Hello James,

I've tested with Opera 11.51 and both online and local upload demos seem to work fine.

Kind regards,
