Nothing that is not self-inflicted I guess. Here's my (famous? :) ) onCellEnter method in DGV base.

    Protected Overrides Sub OnCellEnter(ByVal e As System.Windows.Forms.DataGridViewCellEventArgs)
 '       If Me.Focused = True Then
            If CurrentCell.ReadOnly = True Then
                SendKeys.Send("{TAB}")
                Exit Sub
            End If
            If columnDisabled(e.ColumnIndex) = True Then
                SendKeys.Send("{TAB}")
                Exit Sub
            End If
'        End If
        MyBase.OnCellEnter(e)
    End Sub

Now before I tested me.focused this pushed tabs in the keyboard when one of the columns is "columnDisabled". As a consequence the cell selected is not the one I thought after I Me.STandaardDBindingSource.movefirst, but 20 cells further on the tab path, which looks kind of errrh... sloppy.

(someTextbox)validating (....)
(snip)
        For i As Integer = 1 To 20
            Me.(gridSubmitted)BindingSource.AddNew()
        Next
(snip)
end sub

Checking me.focused solved this, but keyboard clear would have a few hours earlier hehehehehe.
