I have iTunes 9.0.1 running under OS X 10.6.1 on two computers - A Mac Pro and a Mac Mini. On the Mac-Pro, I get the expected behavior when i search directly in song lists. > Click on Music under LIBRARY > Select All (Genres) All (Artists) All (Albums) in the iTunes 8 style top browser > Click on the 'Name column' to sort songs alphabetically > Then start typing, for instance "Hall", iTunes jumps directly to the first song that starts with 'Hall', in my case "Halleluja' by Charlie Parker. On the Mac-Mini when I replicate the above, nothing happens. It looks like the Mac does not respond at all to my typing. Searching the song using the search pane top-right works both on the Mac-Pro and the Mac Mini
