Strange because there is another post in the forum talking about it not working with Chrome & Opera (Problem with anchor link using RapidWeaver 7 with Stacks3, funny enough you are the one who gave the workaround through CSS 
) So, if it works for you I’m clearly doing something wrong, because I can’t get either one to work… Isn’t as simple as dropping an anchor on one page, give it a name, and call it via url/#anchor_name?
