>I am having a few problems with readOnly and visibility in Netscape. I want
to be able to hide a Select box and I've used these parameters to no avail.

Readonly doesn't work in Netscape.

The first one is Explorer-style, so wrong. As to the second one, if 'list'
is a layer it works. However, in order to make it a layer you *must* define
a 'position' in a style sheet (values: 'absolute' or 'relative'). 

If even this doesn't help, place a DIV around the SELECT and give it
ID=list so that the script now works on a DIV instead of a SELECT.
