I have a flickering issue related to the following feature:

I am working in Visual Basic 6.0 service pack 5.

In a mdi application, I have created a form without border. Into this form you will find two controls (a tree view and a list view).

I have attach this form to a DialogBar like this:
With EoForm
Set DlgBar = .CommandSetupBars.AddDialogBar("TaskPanel", xtpBarBottom)
DlgBar.Caption = "Project Browser"
DlgBar.SetSize EoForm.Width / Screen.TwipsPerPixelX, 100
DlgBar.Closeable = False
DlgBar.EnableAnimation = False
Dim frm As frmDocument
Set frm = New frmDocument
Load frm
DlgBar.ChildHandle = frm.hWnd
End With

When I resize the main application border, I get a flickering side effect on the treeview and listview.

If I attach frmdocument as a child window to the main mdi form, I do not get this flickering effect.

What could be the reason ?

Thank you very much in advanced.
Best regards,
Michel.
