The problem is the order. Netscape apparently likes to see URLS like http://www.my.com/this.html#foo?var=data not http://www.my.com/this.html?var=data#foo It chokes on the first, and is happy with the 2nd. IE is happy with either. Any chance this can be checked in as a revision to the tree code to be tested and confirmed? PS - Which is the standard format of the two (as per ww3 or whatnot?) pk
