ah, has 4.0.4 changed the template for editor.css?

I searched for the code in OP

width:20px;
 height:21px;
    margin:2px;

It appears its been changed to this.....

.editor_smiliebox ul.smiliebox li {
	float:{vb:stylevar left};
	height:{vb:stylevar editor_smiliebox_smiliesize};
	width:{vb:stylevar editor_smiliebox_smiliesize};
	margin:2px;
	overflow:hidden;
	position:relative;
	text-align:center;
}

Now after some thought I changed the editor_smiliebox_smiliesize to a bigger size in the stylevars and after mucking about with various sizes in editor2.css I've got a good layout (see attachment)

All I'll need to do now is change the editor_smiliebox_smiliesize in all my other styles and copy the editor2.css from my working good layout to all the others.

Just for info to maybe help others
