Did you ever find a solution? I am having the same problem.
Hiya, I've not necessarily found a solution but I've found a way around it!!
Open up the required photo in Vista with MS Office Picture Manager
You can now open the saved picture in MS Photodraw via Visual Open and work on it.
Hope this helps.
It's a lot of faffing about but at least you can get to work on selected photos with Photodraw.
