I have a combobox on a sheet and when I save the workbook under a new name
and start to perform any actions (i.e. run some code or enter data) the
combobox change event fires. It does this even though I haven't clicked the
combobox or changed the value displayed in the combobox. Also it only does
this once after the file has been saved. After the event fires the first
time it does not fire again if I make any further changes (i.e. run code or
enter data).

Why is the change event firing when I don't touch or access the comboBox and
why is it doing only once?
