A somewhat working patch for ie7 button width issues

gistfile1.css

.ie7 button,
.ie7 input[type="button"],
.ie7 input[type="reset"],
.ie7 input[type="submit"]
{
  margin: 0;
  padding: 0 15px;
  overflow: expression(
    this.style.overflow = 'visible',
    this.style.pixelWidth = function (w) {
      var b, c;
      if (0 == w) {
        // element is probably hidden
        b = document.body;
        c = this.cloneNode(true);
        c.runtimeStyle.cssText = 'position: absolute; visibility: hidden;';
        b.appendChild(c);
        w = c.offsetWidth;
        b.removeChild(c);
      }
      return w;
    }.call(this, this.offsetWidth)
  );
}

/*
 + Only evaluates expression once per button!!!1011 (Not that much performance penalty, that is)
 + Works for buttons in table cells
 + Works for hidden buttons
 - Fails if JScript is disabled
 - Fails if a new longer text string is set from script, but who the **** does that?!? ;)
 - Fails for buttons inserted dynamically
