Possibly this is a latent bug in the 1.5 version of the syntaxhighlighter that will self correct when you can get to version 2.0?

In the interim, for anybody wanting to use the css syntax highlighting, just use the code paste as normal and select the css option.  but, before hitting the "Post" button, click the html button in the editor and fix the class name on the "pre" tag.

Locate this html:

and change it to this:




The result should be some highlighted css:
html *
{
	margin: 0;
	padding: 0;
}
