I've narrowed the problem down -- it has something to do with the enclosing
dialog shell, but I can't guess what:

The XmNactivateCallback DOES get called as expected if the XmText is in a
simple XmForm widget, under my topLevel window, but it DOES NOT get called
if the XmText is in a XmFormDialog, ie. under a dialog shell.

I checked the dialog shell, and XmNdefaultButton is null, and XmNautoUnmanage
is false, so I have no idea why the text widget is not getting the return key.

I know I could add an extra button beside the text field to get an activate
event that way, but I would like `return' to work as it "should", according
to our GUI specification.
