Search Button "Go" not same in IE

[Guest]

I changed the search button. Looks fine in FF but a generic button shows up in IE. I can't figure out why. Please help!

.searchBtn {

	color: #FFFFFF;

	border: none;

	background-image: url(../styleImages/icons/search_button.jpg);

	height: 22px;

	width: 32px;

	font-size: 12px;

	padding: 0;

	font-family: Trebuchet MS, Tahoma MS, san serif;

	font-weight: bold;

}

In FF

In IE
