This one belongs right at the top of the Commonly Asked Questions
list.  Your text widget is in a Form, which is a subclass of
BulletinBoard, which has stolen the Return event to activate its own
default button, even if it doesn't have one.

The cure is to add a translation to the text widget any time after it
has been created, like this:

  XtOverrideTranslations(textWidget,
			 XtParseTranslationTable("<Key>Return: activate()"));

IMPORTANT ANNOUNCEMENT: in everybody's favorite change, this will no
longer be necessary in Motif release 1.1.  To the disgust of the
strict-
encapsulation fans, BulletinBoard will let Text or List children see
the Return key before it looks at it itself.
