Labelsfromlynn,
I've no new info on this since I posted back in The first of 2010. So...if you haven't done it yet, you can file a support case and see if they can help you.
Or...use Firefox with Win 7. That's what I use and it works fine. 32 bit Win 7 and 64 bit Win 7 at home...both work great. It's much easier than hassling with IE, which I never use if I can avoid it.
Hope this helps.
