I have 3 desktops with W7 and I successfully set up the homegroup with all three turned on and running. On each computer, I selected all the boxes to share all libraries. However, when I go to the Libraries window and look under Network, I see each computer, BUT, I am finding that only some of the libraries show up, not all. I shut down and restart the computers as I use them. Nothing changes on restarts. What's wrong and how do I fix it?
