In a stack with a number of fields which must be validated before exit,
I am using an openField handler like this:

on openField
	global currField
	if currField is empty then
		put number of me into currField
	else
		select text of field currField
	end if
end openField

The matching closeField handlers, if the entry is acceptable, put empty
into currField.

I want to move this openField handler to the background by replacing
"number of me" with "number of the target". But the background doesn't
seem to receive the message unless I use a stub "pass openField" handler
in each field. Is this normal, or what?

Please reply by email, unless the answer is something peculiar that
everyone should know:-)
