Thanks gb2world, due to your post I've found the solution:

edit /customer/meta.tpl

and comment out the reference to iepositioning_fix.js, near the very bottom, like so:

{* <!--[if IE ]>
<script type="text/javascript" src="{$SkinDir}/iepositioning_fix.js"></script>
<![endif]--> *}

I think this may only apply to IE7 or earlier (or even IE6 or earlier), but that's just a guess.

(Sorry about all the bold text - as soon as I paste in "/customer/meta.tpl" from my browser, everything is stuck on bold, with no way to turn it off!)
