Bom dia,

Vc pode alterar uma opção no registro do Windows (o que é mais trabalhoso pois para cada usuário que vc precisa ajustar no pc dele), ou vc pode criar um pagina para chamar as outras dentro dela, algo assim:

Code:
Use Windows.pkg
Use DFClient.pkg
Use cComWebBrowser.pkg


Deferred_View Activate_oTesteWeb for ;
Object oTesteWeb is a dbView


    Set Border_Style to Border_Thick
    Set Size to 326 717
    Set Location to 2 2
    Set Label to "TesteWeb"


    Object oComWebBrowser is a cComWebBrowser
        Set Size to 290 705
        Set Location to 29 6
        Set peAnchors to anAll
    
        Procedure OnCreate
            Forward Send OnCreate
            // Set the ActiveX properties here...
        End_Procedure


    End_Object


    Object oPagina is a Form
        Set Size to 13 322
        Set Location to 8 6
    End_Object


    Object oButton1 is a Button
        Set Location to 8 331
        Set Label to 'oButton1'
    
        // fires when the button is clicked
        Procedure OnClick
            String  sURL sFile
            //
            Get Value of oPagina to sURL
            Move "C:\Temp\Teste.html" to sFile
            Direct_Output sFile
                Write '<html><head><meta http-equiv="X-UA-Compatible" content="IE=11">'
                Write '</head><body><iframe src="'
                Write sURL
                Write '" width="800" height="600" allowfullscreen></iframe>'
                Write '</body></html>'
            Close_Output sFile
            Send ComNavigate of oComWebBrowser sFile 0 0 0 0
        End_Procedure
    
    End_Object
