I have an iMac with 10.4.8 installed. I've been using iTunes v6.x for months with no problems. Last week, however, I could open iTunes and start clicking around for about 30 seconds before the rainbow spinning wheel started. I let it go for about 10 minutes before I force quit and now every time I open iTunes the same thing happens. Since v7 came out, I installed the update hoping that would work. That didn't, so I deleted one plist file from /Home/Library/Preferences and an iTunes folder from the /Home/Library and two plist files in /Home/Library/Preferences/ByHost. That appeared to fix the issue for a few days, but now we're back to the same issue. Any thoughts as to what it causing this?
