Hi
We have the same problem with 'Vista and IE7'.
From my experience, for what its worth, it appears that if you use xp with an upgraded IE6 to IE7 there is no problem and all works fine.
The vista version of IE7 does not work, there must be some difference somewhere.
It doesn't matter whether or not you have office 2003 or 2007 it's still the same result.
I have searched the internet over and over but no one can resolve this issue, even RM are stumped, we have had a support call registered with RM for this for at least 6months.
All they seem to be interested int at the moment is pushing CC4.
If anyone has a resolve, fantatsic please let me know
