getPreferredPacketDescription not receiving properly initialized PACKET_DESCRIPTION

    In C# I issue the call:

    preferredpktdesc = m_pdaRecognizer.PreferredPacketDescription;

    According to the docs, the recognizer should first receive a
    zeroed PACKET_DESCRIPTION, into which it should write the
    property and button counts. Next the client side should
    allocate space accordingly and call GetPreferredPacketDescription
    again to retrieve the actual values.

    However, my recognizer receives an obviously non-zeroed
    PACKET_DESCRIPTION, and never gets called again with
    any allocated space.

    Am I missing something or is this a bug?

    Dan, I believe you want to post to the
    microsoft.public.windows.tabletpc.developer newsgroup. This is not the
    programming and development newsgroup.
