I hate to tell you this, but I am looking at the exact same HTML in the Cute Editor and in IE directly, and they ARE NOT doing the same thing.

 

Here's Cute Editor:

 

 

Here's IE6.0:

 

Here's FireFox 1.5:

 

Quite clearly, the editor is not displaying the same as IE or FireFox.  Regardless of what the Box Model recommendation states and which of the three follows it more accurately, IE and FireFox do not do the same thing as the cute editor in this situation.

 

Here's the pertinent HTML:

 

<div id=InfoGalleryStyleByRoom><img style="BORDER-RIGHT: medium none; BORDER-TOP: #e8c25c 3px solid; FLOAT: left; BORDER-LEFT: #e8c25c 3px solid; BORDER-BOTTOM: #e8c25c 3px solid" src="http://cutesoft.net/Upload-Images/IGStyleByRoomSide.jpg">
<div style="BORDER-RIGHT: #e8c25c 3px solid; BORDER-TOP: #e8c25c 3px solid; BACKGROUND: url(/Upload-Images/IGStyleByRoomNav.gif); FLOAT: left; MARGIN: 0px -3px 0px 0px; BORDER-LEFT: medium none; WIDTH: 252px; BORDER-BOTTOM: #e8c25c 3px solid; HEIGHT: 332px">
