Why not just do something like this:
procedure update_text(sequence name)
        text &= "in " & name & "() counter=" & sprint(counter) & "\r\n"

        if remainder(calls, 5) = 0 then
                if not isOpen3 then
                        openWindow(win3, Modal)
                end if
                setText(ctrlText3, text)
-- And here I want the program to STOP and WAIT until the user
-- closes the modal window. If Euphoria/Win32lib had a DoEvents
-- function like Visual Basic, I would write:
--
-- while isOpen3 do doEvents() end while
        end if

--        if not isOpen2 then
--                openWindow(win2, Normal)
--        end if
--        setText(ctrlText2, text)
--        setFocus(win1)
end procedure
procedure onClose_win3()
        isOpen3 = False
        setFocus(win1)
        if not isOpen2 then
                openWindow(win2, Normal)
        end if
        setText(ctrlText2, text)
        setFocus(win1)
end procedure
