Works for me in the May 29th build (2001052904).

It does NOT work for me on Win98 Build 2001053004. There is a blank area under
the category that under IE is filled with a dynamic menu.

I see this as well, if its your first time there you have to choose your zipcode
etc but after that just follow the instructions on here. Its a javascript code
piece so lets try there first. No errors show up in the Javascript Console so we
must not be doing something properly. 

I tested on 0.9 btw so its not a regression.

Marking NEW.

Confirming bug with Mozilla binary 2001052708 WinNT.
It boils down to this URL: 


This URL loads correctly in NN4.7, but in Mozilla it comes up blank in the 
center. No errors in JavaScript console.

The URL directly above uses a <LAYER> tag to show the menu:

<LAYER  WIDTH='100%' SRC='/wv/base/shopping/menu.asp?InvokeCatID=1112901' 

The absolute URL for this is:

If you try the layer URL directly above in NN4.7, you will see the 
menu in question. If you try the URL in Mozilla, it still won't come up,
because <LAYER> tags are employed here as well. 

To summarize: 

1. The parent HTML uses a <LAYER> tag
2. The URL for this itself uses a <LAYER> tag

The browser detection for this site is at:

Sample of the browser detection:

var agt=navigator.userAgent.toLowerCase(); 
var is_major = parseInt(navigator.appVersion); 
var is_minor = parseFloat(navigator.appVersion); 
var is_nav  = ((agt.indexOf('mozilla')!=-1) && (agt.indexOf('spoofer')==-1) 
&& (agt.indexOf('compatible') == -1) && (agt.indexOf('opera')==-1) 
&& (agt.indexOf('webtv')==-1)); 
var is_nav2 = (is_nav && (is_major == 2)); 
var is_nav3 = (is_nav && (is_major == 3)); 
var is_nav4 = (is_nav && (is_major == 4)); 
var is_nav4up = (is_nav && (is_major >= 4)); 
var is_navonly      = (is_nav && ((agt.indexOf(";nav") != -1) || 
(agt.indexOf("; nav") != -1)) ); 
var is_nav5 = (is_nav && (is_major == 5)); 
var is_nav5up = (is_nav && (is_major >= 5));

I can't prove it conclusively yet, but this is almost certainly a 
problem with layers and insufficient or unused browser detection code.

Someone will have to see if they actually use the browser-sniffing file.
When I load the site and try javascript:alert(is_nav), it generates
an error in the JavaScript console: "is_nav is not defined".

At any rate, this is certainly not a JS Engine bug.

I just tried accessing this site using Netscape 6.1PR1 [Mozilla/5.0 (Windows; U;
Win98; en-US; rv:0.9.1) Gecko/20010607 Netscape6/6.1b1] and the menu appeared
correctly.  In the Mozilla 0.9.1 browser [Mozilla/5.0 (Windows; U; Win98; en-US;
rv:0.9.1) Gecko/20010607] the menu still does not appear.  So for some reason
Netscape works and Mozilla doesn't, even though they are apparently using the
same version of Gecko.

This has been happening under the last few Mac milestones as well (0.8, 0.9, 0.9.1 and 
0.9.2), so I recommend changing Platform to "All".

Should this get the evangelism keyword, also? Shouldn't they not be using LAYER at this
