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?

Thanks,

yes it was fixed for 11.2 version. Please replace to

int nAlpha = pGroup->IsExpanding() ? (255 * rc.Height()) / max(1, pGroup->GetExpandedClientHeight()) : 255;
