Hello,
I understood this property this way: if this property is set to true, the height of the control is changed this way that only whole texts are visible; you cannot see the upper half of the last visible line if it doesn't match completely inthe visible area.
I have the feeling that the current behaviour of Runtime and Studio is inverse: if this property is set, the control's height remains as designed and I see the "upper half" of the last visible list item.
I hope I explained well.
Fred
