Report Control: GotFocus event

I have a form with 2 ReportControls and I need to detect when the control has the focus and perform an action on the relevant ReportControl. However, the reportcontrol never seems to fire the GotFocus event.

e.g. Create a new Standard exe. Add 2 ReportControls and a TextBox to Form1, then add the following code to form1

Private Sub ReportControl1_GotFocus()
  Text1 = "ReportControl1_GotFocus"
End Sub
Private Sub ReportControl2_GotFocus()
  Text1 = "ReportControl2_GotFocus"
End Sub
Private Sub Text1_GotFocus()
  Text1 = "Text1_GotFocus"
End Sub
