Problem:
When I click the Action Launcher button on a List View, it does not work.
Answer:
This can happen if the first column of the list view is for an encrypted field. Change the order of the list view columns so that the first column of the list view is for a non-encrypted field.
Action Launcher not visible
If you do not even have the Action Launcher button, see here for possible solutions: I don't see the Action Launcher
