the easiest way i think, would be to create a multiline label and move it around.

you'd need to have it 'hidden' by a shortcut / other label which could cover 3 times the label height.

then you need a 'blank' area in the middle to let the scrolling label through, and use mzScript to set the label text as it scrolls.

the alternative is to tell label.dll to show a huge multiline list, which in turn would need a huge multiline shortcut to hide all the extra lines.
