Unfortunately, there are a lot of annoying differences.

The easiest, the transparency on the gifs may be working just fine. The
problem is, they may not be showing as transparent to their container and
are probably basing their transparency off the background of the page
instead. You may try to set the background color of the body tag
specifically to see if this works.

As far as fonts go, the different browsers often have a slightly different
way of rendering fonts. That's why a text box set for 20 characters in IE
looks like it's the right size, but in Navigator it's about half the size
and doesn't take 20 characters. You may have to manually set the spacing
above and below the font in the CSS to guarantee that it gets a consistant
appearance.

The big problem though, NS doesn't use the same terminology to show and hide
layers. Navigator 4.x introduced DHTML using the <layer> tag. Unfortunately
for them, the W3C rejected this as a way to do DHTML in HTML 4 but Netscape
was committed by that point to their own proprietary way of doing things.
Unfortunately that means you're going to have to change your script and use
a cross-browser script. You should be able to find lots of show/hide layer
scripts at javascript.internet.com, www.dynamicdrive.com and other script
repositories. One such is at:
http://javascript.internet.com/bgeffects/write-layer.html and you can get an
idea of the differences just by looking at it's browser detection routines.
