I'm having a heck of a time figuring this one out.

I've got a 4.5.5 dnn installation running on windows 2000 sp4 fully patched and an SQL Server 2000 db fully patched.  IIS is running dotnetframework 2.0.50727 for this site.  No modifications have been made to the code.  The site was upgraded from 3.x to 4.5.3 to 4.5.5.

This site is working fine, with one exception.  When I'm logged in, I can't get the Module Action Menus to work.  When I hover over any module action menu I get the warning symbol on the bottom left of my browser and the work "Done."  The menu does not display.  (I do breifly get an animated gif that displays over the down triangle icon that represents the module action menu.)  If I double click the symbol I get the following error message:

Line: 213
Char: 17
Error: 'childNodes(...)' is null or not an object
Code: 0
URL: http://www.talenttheatre.com/Home/tabid/53/Default.aspx

This happens regarless if I'm using IE 7 or 6 or FF 2.

I've searched high and low and not found any information.

Any help is appreciated.

Thanks,

Craig
