This is correct behavior. Look at the shape of b. It is being indexed correctly. The problem is that it is ambiguous as to what is wanted when you write b = array([a], dtype=object). We have gone through the rounds on this one and the current behavior is our best compromise. -Travis ------------------------------------------------------------------------- Take Surveys. Earn Cash.
