I had a customer request some help in modifying the default Flex ComboBox behavior such that when the dropdown list was open and a user was scrolling the mousewheel with the mouse outside the dropdown list, the dropdown list would scroll. The default behavior is to close the dropdown list as soon as the user scrolls the mousewheel outside the dropdown list.
