Yes it occurs with IE but i was a having a little trouble with browsercam.com using VNC so haven't been able to test FF2.

As a further test, I deleted the module and page then recreated. After adding one weekly event, assigning to a category and clicking view, then edit, then return the redirect loop started. Just to reiterate this happens on my local machine and the webserver (server 08) running a clean install with URL master and page blaster.

Your welcome to try, you just need to register http://dancecorp.evolveglobal.com.au/courses.aspx then create an event play around with it for a bit and it should either hang if you're using IE or display a timeout if in FF.

It's unlikely such a simple bug to replicate has not been picked up so I'm guessing perhaps there is an incompatibility with URL master or page blaster? Otherwise i am overlooking something silly.

I'd be interested if it happens for you.

Perhaps the stmp settings are playing up, i have manually registered you and disabled URL master for that page. I tried to disable page blaster using an exclude clause earlier today but the page timed out so i may have used a incorrect expression. So i removed that are reset it all up. I will need to either remove it from the web.config or check the exclude but as i need to whip out now i will have to do it when i get back.

You should be good to go now.
