DGV row header won't display in tabs

[Striker77s]

I'm trying to add a title to the row header of a datagridview. I spent hours trying to get it to work to no avail. So finally I started a new project with only the very basic required code. It worked. I then copied the code from the basic project to my full project and the headers refused to show. Here is my code

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Table1 As New DataTable

DGV1.DataSource = Table1

Table1.Columns.Clear()
Table1.Columns.Add("Col1")
Table1.Columns.Add("Col2")
Table1.Columns.Add("Col3")

Table1.Rows.Add(2, 3, 4)
Table1.Rows.Add(5, 3, 5)
Table1.Rows.Add(6, 3, 2)

DGV1.RowHeadersWidth = 80
DGV1.Rows(0).HeaderCell.Value = "1"
DGV1.Rows(1).HeaderCell.Value = "2"
DGV1.Rows(2).HeaderCell.Value = "3"

End Sub

I finally figured out the difference. If the DGV control is on a form it works. If I use tabs and place the DGV anywhere in the tabs besides the first tab it doesn't work. I have two screen shots to show what I mean. Does anyone know why moving the DGV to a tab would break the ability to display row headers.

Any help would be appreciated.

I forgot to mention that I'm using VS 2008.

I downloaded VS 2010 over the weekend and got the same results.
