Balloon Help Toggle

How do I turn off (& on) the balloon help (when you hover over a song, it displays song info in a small pop-up window)? It's a pain when you want to just look at the results list, but it'd be nice to use when you wanted to find out about a particular song.
Thanx,

Right click on the column header in your library > more options > untick 'extended tooltips'
