Gdiplus::Bitmap destruction crash   

Hi,

I have a drawing routine in a class, two different instances alive:

void MyClass::DrawThumb(HDC hdc, RECT rc)
{
    static Gdiplus::Bitmap bmThumb(m_hResource, MAKEINTRESOURCE(IDB_THUMB));
    Gdiplus::Graphics gr(hdc);

    gr.DrawImage(&bmThumb, (INT)(CRect(rc).CenterPoint().x - bmThumb.GetWidth() / 2), m_rChannel.CenterPoint().y - bmThumb.GetHeight() / 2);
}

This compiles (VS2008)  and runs OK under Vista but crashes on some Vista systems when the final destruction is happening i.e. end of _crtMain().
What is the problem?
Thanks,
AR
