I also consider this a bug, but it has always been like in
Revolution/MetaCard.
You may solve this problem by using mouseDown messages or by setting the
lockText to true. This isn't always a good solution, but it is worth a try.
I think it is like this because list fields normally should respond only
to changes in the selection and often a different button just retrieves
the selected line while the list field itself doesn't need to do anything.
Still, I vaguely remember being surprised when I moved from HyperCard to
Revolution and I think both mouseUp and mouseDown should be triggered.
Kind regards,

Confirmed here, and there is nothing in the v6 dictionary that indicates that
the click must occur on a non-empty line to fire the messages.
This is a bug, not a feature, since it is easy to determine if a line is empty
if there is a message sent, and act accordingly, but difficult to do so if
there is not.
I never noticed this before.

Subject: List Field Not receiving Mouse messages unless a line is clicked?
I was trying to find a way to force a list field to unhilite it’s line.
The instinctive behavior would be to just click away from any lines below the
list and then any hilited line in the list would be unhilited. But my handler
doesn’t fire if I click anywhere in the field that is not on a line.
Try this yourself
Create a scrolling list field. The IDE will prepopulated with choice 1, 2, 3
(lines)
Make the field bigger so there is space below those three lines
Add this to the script of the field:
on mousedown
put the hilitedtext
end mousedown
on mouseup
answer "hello" with "OK"
end mouseup
Note that the mouseup message triggers the answer dialog only if you click on a
line.
If you click on the field below.. .nothing happens.
This seems to be a bug to me… since the mouseUP is in the script of the field…
the field show hear it whether or not a line is clicked.
