I have found a problem with the way styles are applied within the WYSIWYG view in FireFox.  If I have the below HTML:

 

<a style="COLOR: red" href="http://www.yahoo.com">test</a>

 

The link appears blue in the WYSIWYG view in FireFox.  In IE, it appears correctly as red.  The HTML works correctly in FireFox when the content is displayed at the final destination, just not in the CuteEditor.
