I noticed a tiny bug in CXTCaption::UpdateCaption.
Bug occurs when changing icon from "real icon" to "null icon".

In CXTCaption::UpdateCaption are following code:

    if (hIcon != NULL)
    {
        m_hIcon    = hIcon;
        DrawCaptionIcon( pDC, rcClient );
    }

So if given icon is NULL, then CXTCaption::m_hIcon wont be updated and
previous icon will be painted when next update occurs (UpdateCaption seems
to work ok before next paint, because it erases background in UpdateCaption also).

Luckily, UpdateCaption is virtual, so it can be override. But that
if (hIcon != NULL) should be removed, set m_hIcon outside of
that scope, etc..
