Ajuda com hwg_EnableMenuSystemItem

[asimoes]

Pessoal,

Estou testando essa função da hwgui e só estou conseguindo sucesso com a primeira instrução abaixo:

hwg_EnableMenuSystemItem( oMainWindow:handle, SC_CLOSE, .F. ) // Aqui funciona (desabilita o X da janela)

hwg_EnableMenuSystemItem( oMainWindow:handle, SC_MAXIMIZE, .F. ) // Aqui não funciona

hwg_EnableMenuSystemItem( oMainWindow:handle, SC_MINIMIZE, .F. ) // Aqui não funciona

Aluguma dica?
