I have a dialog that controls an interactive chart. This has a number of
listboxes, all of which have click events attached. When the user selects an
option in a box (say ListIndex = 4) that produces a combination of choices
that is not allowed, I need to revert the listbox to a permissible option
(say ListIndex =0).

Unfortunately, this just seems to create a new click event that, for some
reason, reverts the ListIndex back to the unpermissible option (i.e. 4) and
repeats the error.

Is there any way to stop these recurrent click events. I have tried using a
static boolean expression and disabling events, but it does not seem to to
stop the macro 'circling' at least twice.
