Okay, I'm not going to ask anyone to write any javascript into their entries, so alternatively, the way to get links to work is as follows:

1) After highlighting your linked word and clicking the link button, the link should look like this:

A HREF="http://www.10d6.com"> link this /A>

2) Once we are that far, add this "target=display" after the link closing quotes, like so:

A HREF="http://www.10d6.com" target=display> link this /A>

3) That should make the links work in a new window.
NOTE: Edited Rudy's links so they work now.
