list field not getting arrowkey msg

[Peter M. Brigham]

I have a list field in one stack that isn't behaving properly. List fields are supposed to allow up and down arrowkeys to move the hilited line. From the dictionary: "If a field's listBehavior property is set to true, and the user clicks a line, the entire line is highlighted. The Up and Down arrow keys move the selection up or down." I have a similar field in another stack that works exactly as expected. The two fields both have their listbehavior set to true -- in fact, AFAICS all their basic properties are the same. I have no arrowkey handlers in any scripts in the misbehaving stack.

Ideas?
