I was running 10.4.11 till yesterday. Now after installing 10.5.4, every time I boot up and get to the finder, a window comes up saying something like, "POPUP PRINTING: No popup printer servers could be found at this time. No popup printing will be possible during this session, blahblahblah..."
It only lets me click "OK", which I do and things proceed to work just fine. It's just an irritating message and I don't know what problems it's trying to make me aware of. Also, it has a lighthouse image to the left of the text. Any help would be great!
