Summary: Screen.ActiveForm  run-time error 91
           Product: Wine
           Version: 0.9.29.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: wine-setupapi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In a VB6.0 project I use the command Screen.ActiveForm to detect the forms 
from where I'm calling a basic form. In wine I discovered if it's not 
available a focus on a control the focus is not set automatically to a 
survival form.
The error assigning for f_parent = Screen.ActiveForm is run-time error 91.
Any one know solution about?
Thanks. Mariano
