ActionListener on JComboBox

Hi,
I have an actionListener registered against a JComboBox and it is acting like an ItemListener in that if I programtically change the selection of the combobox it fires the action - but that is not the behaviour I want - I only want the action to fire if the user manually manipulates the combo box (with the mouse).

Thanks

Herbert,
Pardon me for stating the obvious, but if you

only want the action to fire if the user manually manipulates the combo box (with the mouse)

then wouldn't a "MouseListener" be more appropriate?

[You can use the "addMouseListener()" method that "JComboBox" inherits from class "java.awt.Component".]
Hope this helps.
Good Luck,
Avi.
