Ok, for some reason the Visualizer function on my itunes is not working. It just stopped working about a week ago. I tried to repair permissions several times, but it hasn't helped. My machine: 12" PB 1.33 256 MG most current version of iTunes. any suggestions? thnks!
Duff-Man says...try the other usual troubleshooting tricks - does it work okay for other user accounts on the computer? If it does then it is almost without exception a problem with your preference file. Move the com.apple.itunes.plist from your home/library/preferences (don't delete it in case it is not the problem and you want to use it again) and launch iTunes again - if the problem is gone, just reset the rest of your preferences again and you are all set....if the problem remains then it is something else....oh yeah!
Duff-Man, Thanks for the help. It turned out that the Preferences were indeed the problem. All is well now.
