UPDATE: When I converted the .js file to the .css file and updated the includes, per the instructions found at http://www.udm4.com/manual/final/noscript/
, the nav bar was finally rendered correctly in all browsers.
However, now the menus do not display in IE 6. (They still work perfectly in IE 7 and FF 2.)
Furthermore, when I revert all of the code to the original installation files, everything works except for IE 6. In other words, the menus look the the default menus, but the sub-menus do not display in IE 6.
Therefore, it seems like the issue is isolated to IE 6 only.
Hopefully, this will help jog someone's memory on the forums.
Any help is GREATLY appreciated!
