Onenote 2007 SP2 Windows 7 Home Premium 64-bit Login is an admin account Sometimes when changing sections within a notebook, Onenote is bringing up a dialog asking whether I want to open the whole notebook, or just a section. The notebook I would be opening is the same one I'm already in. Choosing to open the whole notebook, I get another copy of the same notebook listed in my Notebooks bar on the left of the screen, which then starts synchronizing.. apparently with itself. Checking the properties, the location of my original notebook is what I expect it to be, in CUsers\AccountName\Documents... etc. The location of the 2nd notebook is similar, but is prepended with my account name and the computer name. It's like OneNote is accessing the notebook again through some kind of network location. It's not a shared notebook, and I had no problems before my fresh Windows 7 install. The computer was previously using Vista 32-bit. Can anyone help me figure out what is going on here?
