I found a Christopher's answser on 4/23/09 to a similar problem; basically
you just register a function on the "onscroll" event of the scrolled pane an
call map.updateSize();
It works for me, let me know if it's the same for you.
Thank's a lot to Chris...

 call map.updateSize() on the map after the pane is scrolled, perhaps? We
may only look at scroll distances at the document level; I don't recall
looking into this issue on sub-panes before.
