I notice every now and again my address book opens and closes. I have not found a trigger, at least in what I am doing at the time. I have not installed anything new. Anyone else have something like this going on? If this was a windows machine I would think spyware. I am hoping it is an easy fix, but I have not seen/heard anything like this yet. Running a MBP Core 2 Duo 2.33 OS X 10.4.9 2 GB ram Thanks for the help.
