Did you find a solution to this issue? I am having the same problem. Any help is appreciated.
I ended up opening a ticket with support. After a few weeks they basically told me it wasn't going to be fixed in 8.8. This is an excerpt of the email I received:
"Engineering has investigated this issue and it will not be fixed until the next release of 9.0 currently scheduled for 3rd quarter of 2011. You will need to upgrade to the new version when it is released if you want this functionality in Windows 7"
Which was fine with me because we plan on upgrading to 9 this summer anyway. I hope this helps!
