Can you provide a link or reference to a location within the 
specification that prohibits the use of "_"?  I looked through several 
versions of the CSS and HTML and xHTML specifications and saw no mention 
of the use of "_" in class or id names being illegal (or even discouraged).

Also, the W3C's CSS Validator ( http://jigsaw.w3.org/css-validator/ ) 
says the CSS is valid (only providing an error on "Property behavior 
doesn't exist"--for the IE PNG transparency hack) on the pages I 
checked.  The HTML Validator ( http://validator.w3.org/ ) also doesn't 
complain about the id/class names (showing only a few (i.e. 13 for the 
home page) minor errors--most (8 for the home page) of which were the 
lack of ALT text for images).

Are you sure this wasn't just an issue of browser caching that you 
"fixed" by changing names, causing the browser to reload the CSS?  (I.e. 
did you try a Shift-Reload and/or clearing your browser cache?)
