[iTunes] iTunes will not allow tunes to be added to playlists

[Scott Stamper]

All,

An update.

Just as soon as I sent my first mail, I tried double clicking all the  
tunes which I tried to select for a playlist. If I double clicked each  
tune, the exclamation point disappeared, and I could then add the  
selection to the playlist.

I obviously don't want to double click every tune I want to add to a  
playlist.

Help!
Scott
