It's definately a Vista thing.
Iv'e dealt with this with Home Premium
For some reason Vista will show bucket.MDB but not the songs or songs backup.MDB (in the database folder) unless I click the "compatability files" button at which time songs will show up but bucket will disappear.
I've found a whole host of things I don't like about Vista, especially the fact that I have to go through 4 separate confirmations just to create a new empty folder. Major pain in the backside.
