Wow, AOL should do something about that. We can't just disconnect you from your ISP with a web page. If that were possible, lots of malicious sites out there would do things like this.
Can you try going to this page:
http://www.auctiva.com/profiles/intl_detail.aspx
I want to see if the problem is with the html editor itself or the listings page. Let me know if you can get to the detail profile page without any trouble and we can work from there.
