単一選択モード(SingleSelect)でフォーカス枠の右辺が表示されません。
拡張選択モード(ExtendedSelect)や複数選択モード(MultiSelect)でも同様の現象が発生します。
【手順】
1.新規フォームにSPREADを配置します
2.下記サンプルコードをコピーし、アプリケーションを実行します
--フォーカス枠の右辺が表示されません
【サンプルコード】
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' SPREADの設定
FpSpread1.ActiveSheet.ColumnCount = 3
FpSpread1.ActiveSheet.OperationMode = FarPoint.Win.Spread.OperationMode.SingleSelect
End Sub

回避方法
Service Pack 6（v7.0.2019.2008）で修正済み。
Service Pack 6（v7.0.2019.2008）より前のバージョンでは次の回避方法が有効です。
------------------------------------------
FocusRendererプロパティに独自のレンダラを設定します。
