additional info: I thought the laptop was freezing predictably when I got interrupted to answer the phone, etc. Today, I took a BR break -- when I returned, the cursor was flashing (good!) but as soon as I touched the Trackpoint, it froze (bad!). Anyone think this is a Trackpoint issue, a docking station issue or a network issue? I also wondered about my Windows backup program, but my backups are occurring on schedule, so it's not like it's trying to back up and can't.
