Since it's a bit easier to work on an issue like this via ticket (because we can see the issue, and work on it with you) - it would be great if we could try that... Are you still unable to post to the ticket?
If you're able to see the ticket, which is using the SSL certificate, I don't think you should be prevented from posting... The response window is a 'pop-up' - do you have a pop-up blocker enabled that would be killing the window?
