JS menu - works in Firefox 3 but not in IE7

[littlealex2009]

Hi there - I hope someone can help me - I have the following page with a JS menu in it from dynamicdrive.com:

http://jemmakidd.com/products.php

The menu in the link above works perfectly in Firefox but in IE7 there is what looks like a missing image on the right of each top menu item - I have attached a screenshot to show what I mean...the 'sub-menu' items are also aligned right in IE whereas in Firefox they are correctly aligned left...

Here is my css:

.jquerycssmenu{
font: bold 12px Cordoba;
border-bottom: 0px solid black;
padding-left: 15px; /*offset of tabs relative to browser left edge*/
}

.jquerycssmenu ul{
margin: 0;
padding: 0;
list-style-type: none;
}

/*Top level list items*/
.jquerycssmenu ul li{
position: relative;
display: inline;
float: left;
}

/*Top level menu link items style*/
.jquerycssmenu ul li a{
display: block;
background: transparent url(glossy_back220x23.gif) top center repeat-x;; /*background of tabs (default state)*/
padding: 5px 7px 4px 7px;
margin-right: 3px; /*spacing between tabs*/
border: 0px solid #778;
border-bottom-width: 0;
color: #D2005A;
text-decoration: none;
}

.jquerycssmenu ul li a:hover{
background-image: transparent url(glossy_back2.gif); /*tab link background during hover state*/
}
	
/*1st sub level menu*/
.jquerycssmenu ul li ul{
position: absolute;
left: 0;
display: block;
visibility: hidden;
border-top: 0px solid black;
}

/*Sub level menu list items (undo style from Top level List Items)*/
.jquerycssmenu ul li ul li{
display: list-item;
float: none;
}

/*All subsequent sub menu levels vertical offset after 1st level sub menu */
.jquerycssmenu ul li ul li ul{
top: 0;
}

/* Sub level menu links style */
.jquerycssmenu ul li ul li a{
font: normal 13px Verdana;
width: 135px; /*width of sub menus*/
background: transparent url(glossy_back2.gif) repeat-x bottom left;
color: #D2005A;
padding: 4px 5px;
margin: 0;
border-top-width: 0;
border-bottom: 0px solid black;
}

.jquerycssmenu ul li ul li a:hover{ /*sub menus hover style*/
color: #D2005A;
}

/* ######### CSS classes applied to down and right arrow images  ######### */

.downarrowclass{
position: absolute;
top: 7px;
right: 5px;
}

.rightarrowclass{
position: absolute;
top: 5px;
right: 5px;

Here is the link to the js menu code I used:
