Appliction crashed because of Xtreme

I have recently moved to Xtreme Toolkit Pro v10.1. Every thing seems to be working fine except that my applicant crashes in one scenario. When I terminate my application with PostMessage(WM_QUIT) my applicant crashes  in "void CXTTabBase::OnPaint()" @ "GetPaintManager()->DrawTabCtrl(&memDC, this)" line. I think xtreme theme manager is working in its seperate thread when I was terminating my application.  How can I tell xtreme to stop all its activities.

Note: Applicant was working fine with xtreme 4. sth version.
