    Boa tarde! .. pra todos!!!

    Preciso da ajuda de vocês,

    Tenho uma função que trava a roda do mouse no formulário.. que funciona no sistema operacional - 32 bits.
    Acontece que preciso dessa função para que funcione no - 64 bits.
    Tentei.. de acordo com algumas pesquisas "acertar pra funcionar".. mas, não deu certo!
    Agradeço, antecipadamente, a ajuda!!!
