I must be misunderstanding your concerns because I can't duplicate the
effect I think you are describing.

Your phrase "work the buttons" to me means that the buttons get focus and
their onClick event fires. I cannot get the ctrl-char combination to do this
whether fields are disabled or not.

The ctrl-S convention is not automatic. If you want this combination to do a
"save" operation for you, you must trap it yourself and handle the work.
Ctrl-char is not meant to "work the buttons".

Here is the code that I used to test for this effect.
------------------
include win32lib.ew
without warning

integer win, btn1, btn2, fld1, fld2, cb1, SB

win =  create(Window, "Test",    0,   0,  0, 400, 400, 0)
SB  = create(StatusBar, "", win, 0, 0, 0, 0, 0)
btn1 = create(Button, "&NEXT", win,   5,  5,  60,  25, 0)
btn2 = create(Button, "&ABORT", win, 85,  5,  60,  25, 0)
fld1 = create(EditText, ""     , win,   5, 55,  60,  25, 0)
fld2 = create(EditText, ""     , win,  85, 55,  60,  25, 0)
cb1 =  create(CheckBox, "a &check box caption", win,   5,105,  260,  25, 0)

procedure clicker(integer self, integer event, sequence params)
    setText(SB, getText(self))
    setEnable({fld1,fld2}, isChecked(cb1))
end procedure
setHandler({btn1, btn2,cb1}, w32HClick, routine_id("clicker"))
setHandler({fld1, fld2}, w32HGotFocus, routine_id("clicker"))


WinMain(win, Normal)

The text is coming from the second parameter of the CheckBox's create(). It
is the caption. The space to display the caption is defined by the 6th
parameter. Maybe you haven't defined enough room for the entire caption to
display. The dotted line is Windows way of telling you that the checkbox has
focus.
