[Zope-dev] Photo Product Strangeness

I've been messing around with the Photo product, and I've noticed something odd about how it handles changes to the display sizes: When you create several Photo objects in the same folder (not in a ZPhotoAlbumPage), they affect each others display sizes. For example, changing one of the display sizes in one Photo will change the corresponding display in sibling Photo. Can anyone suggest how to fix this? Michael Bernstein.
