I used the drop down menu generator to create 5 menus located in table. in IE and NS6 they work fine, but ns4 keeps looking for the default url <a href="alternate.htm" onClick......> that was supplied by the generator, and not using the "onClick" event . in note from generator it states that older browsers look for this url - to make it backward compatible. It also displays the drop-down menu link selections right on the page in one long column. I have not modified the code except to add in names of my links.
Has anyone come across this yet? - thanks

You did place them inside table cells which in NS4 will sometimes not work corectly when you mix layers and table cells togehter. Try the code without placing it inside a table and see if it works. Also you might want to check out the Menu/Navigation script at

Not sure if it is NS4 compatible, but it is much nicer and has excellent instructions on how to implement it. Good Luck.
