Control is invisible in dynamic report width

[Vensia]

Dear all,

I design a simple report. The report width is 4 inch and has a label
control.

Label control
--------------
Name : Label0
Left : 0
Caption : Hello
Width : 0.5 inch

I add the following code :

Private Sub Report_Open(Cancel As Integer)
Me.Width = 6 * 1440
Me.Label0.Left = 5 * 1440
End Sub

Then I preview the report, why the label control is invisible ?
Thanks.

Regards,
Vensia
