Thanks,
yes it was fixed for 11.2 version. Please replace to
 
int nAlpha = pGroup->IsExpanding() ? (255 * rc.Height()) / max(1, pGroup->GetExpandedClientHeight()) : 255;

I have a case in which I am crashing in CXTPTaskPanelPaintManager::DrawGroupClient because in the line

    int nAlpha = pGroup->IsExpanding() ? (255 * rc.Height()) / pGroup->GetExpandedClientHeight() : 255;

pGroup->GetExpandedClientHeight() is returning 0, resulting in (surprise) a divide by zero.  I installed a little defensive programming in this function to prevent the crash.  It may be that I don't have something set up correctly, but a bit more checking in the DrawGroupClient code doesn't seem unreasonable to me.

I am running 10.4 and see that the source hasn't changed (in this function, anyway) in 11.1.  Has this been fixed in 11.2?
