iTunes 8 - Trying Hard to Earn a Buck

iTunes 8 is really reacting to the economic climate. Today I tried to purchase a song that I forgot I had already purchased via iTunes a while back. After clicking "buy", iTunes offered me two choices:

1. Upgrade to iTunes Plus (later discovered was $119 to enable)
2. Buy the song again

There is no "close" button. I could not close the dialog... at ALL. I couldn't even "Quit" iTunes via the menu, I had to FORCE QUIT to get out of this state.

What the heck?
