Tabs do not appear in window-can't shift to other sheets in workbook

I am having problems with my tabs as well. I have the Sheet tabs checked off but they still do not show. I am using excel 2000.

Or, you can try this code:

Sub Test()
    ActiveWindow.DisplayWorkbookTabs = True
    For Each sh In ThisWorkbook.Sheets
        sh.Visible = True
    Next sh
End Sub
