vertical alignment

Just updated Component Pack to v6.7.1.0, and now I have lost vertical centering on multi-line cells.  The first line is centered, and all other lines are below.

These are the control settings, that are same as before upgrade.
 sg->Multilinecells = true;
 sg->WordWrap = false;
 sg->VAlignment = vtaCenter;
Is there a new setting that affects this?
Note that I upgraded OS from WinXP64 to Win764 at about the same time.

We have traced & solved this issue. Next update will address this.
