Hi all,

I have a problem using tabbox element in my XUL page.

I have the following XUL file:

Test.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin" type="text/css"?>
<window title="XUL Periodic Table"
        xmlns:html="http://www.w3.org/1999/xhtml"

xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<vbox flex="1" style="overflow: auto">
<groupbox>
<description>
  This is the standard tabbox.  It looks fine.
</description>
<groupbox>
  <tabbox  flex="1">
    <tabs >
       <tab label="Default"     />
       <tab label="Tab"         />
       <tab label="Orientation" />
    </tabs>
    <tabpanels flex="1" >
       <label value="Default" />    
       <label value="Tab " />        
       <label value="Orientation" />
    </tabpanels>
  </tabbox>
</groupbox>
</groupbox>
</vbox>
</window>

(Code from: http://www.hevanet.com/acorbin/xul/top.xul)

The file opens fine when opened using file or chrome protocols. But when I
try to open the same using http on Fx1.5.0.3 (this was built from source with
default build configurations) the tab panels don't appear. Neither am I able
to switch between tabs. Other files which do not contain tabbox work as
expected. Also, the file opens fine when accessed using http from the mozilla
application installed.

I use Fedora 4, and the http server(Apache 2.0) that ships along. The
application type is set in mime.types.

Any help in this regard would be greatly appreciated.

Regards,
Aruna.
