When is SESSION:FIRST-CHILD = CURRENT-WINDOW
When the CURRENT-WINDOW system handle is explicitly set via the 4GL
(ASSIGN CURRENT-WINDOW = window-handle), Progress moves that window to
the head of the chain of windows. Therefore, SESSION:FIRST-CHILD will
equal CURRENT-WINDOW.
It is also possible for the CURRENT-WINDOW system handle to change
implicitly; for example, when the current window is destroyed Progress
chooses another window to be CURRENT-WINDOW. In this case, Progress
does not move the window to the head of the chain of windows and
SESSION-FIRST-CHILD will not necessarily equal CURRENT-WINDOW.
