[iTunes] Interactive Booklet... Isn't Interacting?

[joAnn ortiz]

Hi all,

ok, so maybe this is petty, but it's annoying me. My interactive  
booklet for AFI's DECEMBERRADIO has ceased working - and I have no  
clue as of WHEN since I don't usually sit and stare at my screen when  
I play music though iTunes. i'm using PB G4, OS 10.4.8, iTunes  
7.0.2.  when I click on the booklet/movie to play it the progress bar  
whizzes by while the message "Album Artwork Not Modifiable" displays  
in the art window. actully, the same scenario exists on my lampshade  
iMac same software specs & a mirrored library. Any ideas?

Many thanks,

joAnn
