I am looking for a way in Acc2003 to change the sorting of a combo
box, depending if the user holds down the Shift key when clicking the
combo box (i.e. no shift key = sort order (A), shift key down = sort
order (B)).

I have tried changing the combo boxes .RowSource in the On Mouse Down
event (which works) and checking for the Shift key, but this somehow
prevents setting the selected item in the dropdown list. Actually
just setting the existing .RowSource in the On Mouse Down prevents
item selection in the dropdown list.

Any ideas ??
