Fieldset squashed

I have a div element with a fieldset inside it. It looks fine in Chrome, Firefox, and Safari, but in IE it is squashed against the right side, and all the text is overflowing the fieldset, while the fields in it are squashed down.

Here is my html:

<div className="body">         <fieldset>
	(fieldset content)</fieldset></div>

And here is my CSS:

.body {
    margin-top: 20px;
    margin-bottom: 10px;
    margin-left: -6px;
}

.comboBox {
    background-color: #E2E2E2;
}

.element {
    float: left;
    margin: 5px;
}

.ItemsScreen .Modal-dialog--normal {
    max-width: 1000px;
}

.quantityField {
    width: 14%;
}

Any help appreciated!
