Howdy, Running iTunes 6.0.4 on an iMac G5 w/ 10.4.5 and for about a month now itunes has been running very slowly. Very annoying. It has to stop and think about everything and the beachball (or whatever it is) icon just sits there spinning, not allowing me to change songs for a few seconds or so. It was never like this before. Note: I had the same problem with the previous version of itunes as well. Everything else on the computer runs very well. Could it be because of my library size (40 GB)?
