I added scrollbars=0, or 1 or 2 to the editorSourceStyle string...   HTML editor doesn't change..   Even set it to "x".  Did not get an error, so I assume it is ignoring it...

var _editorSourceStyle = "font:normal 11px verdana;background:#ffffff;margin:0;padding:0; scrollbars=1;";

Any other suggestions or more detail would be greatly appreciated...

thanks..
