um, maybe that test() function should be slightly changed, like this
(although yview() does not seem to complain about negative indices):

def test(event):
    i = 597
    wd = event.widget
    wd.selection_clear(0, 'end')
    wd.selection_set(i)
    wd.update_idletasks()
    h1 = wd.winfo_height()
    i1, i2 = wd.nearest(0), wd.nearest(h1)
    index = i - (i2-i1)/2
    if index < 0:
        index = 0
    wd.yview(index)

Best regards

Michael
