I am implementing a design that uses custom styled submit-buttons. They are quite simply light grey buttons with a slightly darker outer border:

input.button {
    background: #eee;
    border: 1px solid #ccc;
}

This looks just right in Firefox, Safari and Opera. The problem is with Internet Explorer, both 6 and 7.

Since the form is the first one on the page, it's counted as the main form - and thus active from the get go. The first submit button in the active form receives a solid black border in IE, to mark it as the main action.

If I turn off borders, then the black extra border in IE goes away too. I am looking for a way to keep my normal borders, but remove the outline.
