Set calculation to manual and disable Excel events and see if the problem
goes away.

If it does, then there is some relation to your action of populating B2 and
a range the listbox is associated with.

Hi Tom,

Thanks for your help. But, B2 is not in the listfillrange... in fact,
the listfillrange is set to a named range that refers to data on an
entirely different sheet!
