Don't know the script, but I assume it uses lots and lots of layers. 
Netscape 4.5 and 4.6, especially, are very vulnerable to too much layers 
(sometimes combined with lots of style sheets).

As a rule of thumb, don't use more than about 10 layers on a page, and even 
then NN4 may crash. Generally the crashing danger is less in NN4.05 and 
before and NN4.7x (but this is of course only a *general* rule).

When you have implemented such a script, do the Resize test by loading the 
page into NN4, resizing it at least 5 times and see how the page holds up. 
If the browser crashes, repeat the test, if it crashes on three consecutive 
tests the script is definitely dangerous and should not be used.
