IE10 issue with treegrid scrollbars

Hi,
I am using SmartGWT EE 4 (SmartClient Version: v9.0p_2014-01-13/Enterprise Deployment (built 2014-01-13)) and I observe a strange issue in IE10 (and earlier IE versions), which I can not reproduce in FireFox 26.

When I expand the nodes in a (large) tree grid, it starts to show vertical scrollbars. But when I try to scroll to the bottom of the treegrid, the whole browser starts to flicker and the scrolbar never reaches the bottom.

This does not happen in FireFox.
