Richtextbox resized smaller, vertical scrollbar disappears. Any idea how to fix this?

I know the current version of Visual Studio has this bug fixed, but does anyone know of a way to correct this with VB 2010, 4.0 NET?

I tried to programmatically double click the richtextbox when I resize the form to get the vertical scrollbar to reappear, but that doesn't work.

Code:

---

If Me.Height <= t Then
            RichTextBox2_DoubleClick(sender, e)
            t = Me.Height
Else
End If

---

Any ideas besides upgrading?

Still using VB10 on Win7 here, When I have RTB resize with form (anchored on all sides) invalidating the RTB in forms resize-end event works here,...

Code:

---

Private Sub FrmMain_ResizeEnd(sender As Object, e As EventArgs) Handles Me.ResizeEnd
    RTB1.Invalidate()
End Sub

---

Other workarounds, might be to toogle the rtb ScrollBars property,

Thanks Edgemeal! This did it for me:

RichTextBox2.Invalidate(True)

Also, to prevent that funky scroll to caret in the richtextbox while resizing the form, I give a hidden label focus in the form's 'Resize' event, and refocus the richtextbox on it's 'MouseEnter' event.

Code:

---

Private Sub Form1_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize     
        Label1.Focus()
        RichTextBox2.Invalidate(True)
End Sub


Private Sub RichTextBox2_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox2.MouseEnter
        RichTextBox2.Focus()
End Sub
