Why is my button not working in Internet Explorer when it works in all other browsers? Shouldn't the 'border-radius' property work for IE as well?
.simpleHelp {
border-top: 1px solid #ffffff;
background: #910330;
background: -webkit-gradient(linear, left top, left bottom, from(#790228),
to(#910330));
