title: Excel Control events trigger on application close
body: <p>I've an Excel-workbook with ActiveX controls on worksheets (not on Userform!). When I close the workbook (without closing Excel) everything works well, but when I close Excel entirely it triggers Change events of ActiveX Comboboxes on the worksheets. This creates errors because it seems that Excel has done some cleaning already by removing controls. </p>
  
  <p>How can I bypass or solve this? These events shouldn't trigger in the first place because no values are changed on close. </p>
