You can get that error from firewall software, or pop-up blockers, or a number of other things. I think it happens if you're working from cached pages too. He might try disabling any software firewall he has temporarily and trying to post. Or configuring it to let through anything from axiomaudio. (You should be able to add www.axiomaudio.com as a trusted site.) That could be the problem.
