Why does pressing RETURN in a text widget do nothing?

happens using Motif 1.0 when I have a text widget inside a bulletin board (or form) inside a dialog shell. (In Motif 1.1 it is fixed for both text and list widgets.) Answer: In single line mode, pressing the key usually invokes the activate() action, and in multi-line mode, the newline() action. However, whenever a widget is the child of a bulletin board widget which is the child of a dialog shell, the bulletin board forces all of its children to translate to the bulletin board action Return() which is usually associated with the default button of the dialog. To restore the text actions of activate() or newline(), you need to overide the Return() action of the bulletin board.
