I have a tool that inherits BaseCommand.  It's set as a Toggle button to be toggled on when editing and off when not.  When toggled on the caption should read "Stop Editing" and when Off it should read "Start Editing".  The code below worked fine in 9.3.1 but for some reason the caption no longer changes.  Any ideas? Public Overrides Sub OnClick()
        'TODO: Add StartStopEditing.OnClick implementation
        Dim pID As New UID
        Dim pfLayer As IFeatureLayer = Nothing
        Dim pDataSet As IDataset = Nothing
        Dim pMxDoc As IMxDocument = Nothing
        'Start/Stop Editing Sign workspace
        Try
            pID.Value = "esriEditor.Editor"
            _pEditor = m_application.FindExtensionByCLSID(pID)
            pMxDoc = CType(m_application.Document, IMxDocument)
            pfLayer = pMxDoc.FocusMap.Layer(GetIndexNumberOfLayerName(pMxDoc.ActiveView, sLayerName))
            pDataSet = pfLayer.FeatureClass
            If _pEditor.EditState = ESRI.ArcGIS.Editor.esriEditState.esriStateNotEditing Then
                _pEditor.StartEditing(pDataSet.Workspace)
                MyBase.m_caption = "Stop Editing"
                MyBase.m_checked = True
            ElseIf _pEditor.EditState = ESRI.ArcGIS.Editor.esriEditState.esriStateEditing Then
                MyBase.m_caption = "Start Editing"
                MyBase.m_checked = False
                _pEditor.StopEditing(True)
            End If
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub
