Comments disappear if I append "index.html" onto address

Hi,

I recently installed IntenseDebate on my website and have discovered a problem.

I registered the URL of my website as, say, http://www.google.com. If I go to the site in a browser the comments show up as expected. However, if i put the full address of my site into a browser, say, http://www.google.com/index.html, the comments are empty.

Am I doing something wrong or have I discovered a bug?

Thanks,

Neil
