Try the following code in your head tag

<script language="javascript">
document.onkeydown = function (){
if (122 == event.keyCode) {
document.location.reload();
}
}
</script>

Haven't had a chance to test but hopefully this will reload the page and at least display it better.

Alternatively changing document.location.reload(); to:

event.keyCode = 0;
return false;

should ignore the F11 keypress, if this works you may want to detect ie before performing in order to maintain functionality in firefox and other good browsers :D

Interested in knowing if this works
