Workbook_Open() events won't run

Hi, I have a workbook that has several macros running fine; however, when I close the workbook and do not exit the Excel Application, but then reopen the same workbook I find events in the Workbook_Open() won't run, but yet all of the macros still run. I don't want the users to have to completely exit the Excel Application every time they finish using this workbook.

I have turned off the toolbar in the Workbook_Open and then turned the toolbar back on when the user exits the workbook via a macro button that has the code in Module1.


In ThisWorkbook...

Private Sub Workbook_Open()
 	Application.ExecuteExcel4Macro "SHOW.TOOLBAR(""Ribbon"",False)"  
        Application.DisplayFormulaBar = True
End Sub

In Module1...

Public Sub ExitWorkbook()
        Application.EnableEvents = False
        Application.DisplayAlerts = True
        Application.ExecuteExcel4Macro "SHOW.TOOLBAR(""Ribbon"",True)"
 	ActiveWorkbook.Close
End Sub

Any ideas why the events in Workbook_Open() won't run when I reopen the workbook?

I thank you in advance for your help.

Thank you TMS. It didn't dawn on me .EnableEvents was an application level property. My dilemma has been solved. Thank you very much
