When I created the links, it was all automatic - I chose to insert a navigation bar with links to child pages or same level pages or whatever, and FrontPage made all the hyperlinks for me. Here is the scripting for a page that opens the links listed on it into another browser window (see below). My website is robandcob.com - for instance, when you choose "Photos" from the homepage it opens that one okay, but when you choose "2005 Photos" from there, it opens another browser window. To my knowledge, I did nothing differently. Do you see anything here?
