Flash.text.textfield.ScrollV no more works with newest flash player 10.1

Question

Scrolling textfield is no more working with player 10.1.82

My code is: SCROLLV = SCROLLV +2

text is scrolling down nicely with older players, but now with newest player it never scrolls.

scrolling WORKS OK with player: 10,0,12,36

scrolling FAILS with player: 10,1,82,76
