Tabs in IE have a text select cursor rather than hand pointer

I noticed in IE6 and IE7 that the mouse cursor showed as a text selection cursor when hovering over the tab span element. Firefox was fine.

The fix was to add a specific cursor definition in tabs.css:

  ul.primary li a .tab
  {
    display: block;
    height: 20px; /* 24px (parent) - 4px (padding) */
    margin: 0;
    padding: 4px 13px 0 6px;
    border-width: 0;
    line-height: 20px;
    background: url(images/tab-right.png) no-repeat right -38px;
    cursor: pointer;
  }

Should this live in the ie.css instead though?
