I did not see this specific problem mentioned before, have others found it?
(MS Pub 2003,  service packs up to date)

The navigation bars created by the Nav Wizard in my web pub did not work  
when tested with Firefox although, they worked fine with IE. When I say they
didn't work, I mean that Firefox did not even recognize them as links.   My
quick  workaround was to make my  own nav  bars with a text box and putting
hyperlinked texts inside the box, then copying to each page, deleting the nav
wiz bars.   A couple of extra minutes, but it works. until I figure out if  I
did the Wizard incorrectly.

Also, it seems that if you have any overlapping objects in the design, like
ovelapping pictures or text boxes that are hyperlinks, those links don't work
in Firefox ( by overlapping I don't mean just what you see, but the dotted
lines that define the area, of the object.  IE doesn't have a problem with
this it seems, so   the web review feature and  even live review with IE is
not enough to assure a good web design. Hot spot hyperlinks  that are
overlapped by other objects seem to be OK.  ( I first  publish to the desktop
and then open the index file in the folder with different browsers before
publishing to the server and more testing.)
 
Any similar problems or workarounds?  Thanks to all the MVP's who have
steered me away from other problems.
