OK ... I've been fiddling, and have changed the javascript code just a bit. No, I don't know what I'm doing, but received advice from the fellow who actually wrote the code at Snitz ...
So, I tested it on my machine ... I have v4.79 - the latest version of Netscape, other than the "all-new" 6.2. Whatever did they do with version 5, anyway?!? No matter ...
It works here ... I tested post preview & I tested the members area and was able to move past the first page. I must say, though, that the site looks much better in Internet Explorer 6.
