It's because you have applied the behavior's event directly to the <marquee>
tag -
<marquee behavior="alternate" bgcolor="#FF8000" width="49" height="26"
onclick="FP_openNewWindow('626', '495', false, false, false, false, false,
false, '', /*href*/'buffet.htm')">See it!</marquee>
Try changing that to this -
<marquee behavior="alternate" bgcolor="#FF8000" width="49" height="26"><a
href='buffet.htm' target="_blank" onclick="FP_openNewWindow('626', '495',
false, false, false, false, false, false, '', /*href*/'buffet.htm');return
false;">See it!</a></marquee>
which should give you what you want. In addition, I have added a little
extra in that now the link will work, even though someone has js turned off
in their browser.
By the way, if you copy and paste from this post, make sure you put that
whole thing on a single line.
And remember - if you don't get the 'finger' look at the code. Chances are
good you have applied the behavior event to the wrong page element.
