I made this change:

constant EditText4 = createEx( EditText, "123", CWindow3, 8, 28, 48, 20, 0, 0 )
openWindow(CWindow3,Normal)

and it doesn't change the behavior. I still need the w32HActivate for the
EditText control.

The problem I see is that setting focus will highlight (select) the data and
that may not always be desirable.
