In IE, the syntax is written out correctly for an anchor on the current page: href=#date

 

However, in gecko browsers, it puts in the full relative path:
href=/Portal/EditModule.aspx?tabid=174&mid=824#date

 

I cannot replicate this on your demo page. I am using relative URL's in my portal.

 

Is there a configuration somewhere that will prevent this?

 

THANKS
