Oh no... I understood. What I was saying is that if there is a mod_rewrite call being done somewhere, it's outside of the calendar, hence outside of our control and basically impossible for us to troubleshoot. I would suggest you look in every folder that is above the calendar in it's hiarchy up to the web root. And then the apache config file. If your site is hosted by a hosting company, they would be much better suited to help you find where this is coming from.
As a side question, are you using a content management system? Maybe it's caused by it. If you're willing to give me access to your system, you can send me the relevant information by using the link in my signature.
