I have a main window (call in MAIN_WINDOW) that fills my entire screen.

I have two other visible windows, children of MAIN_WINDOW, that do not overlap
each other (call then WINDOW_1, WINDOW_2).

I create a third window (call it ON_TOP) a child of MAIN_WINDOW and set its x,y
coordinate
so that when it is mapped, it is on top and partially obscures WINDOW_1 and
WINDOW2.

When I XDestroy ON_TOP, I'm not getting Expose/Visibility Events for WINDOW_1
and/or WINDOW_1.


NOTES:

1) All windows are created with XCreateSimpleWindow, mapped with XMapwindow
and then destroyed with XDestroyWindow.

2) MAIN_WINDOW is set as XSelectInput (the_display, MAIN_WINDOW,
SubstructureNotifyMask |
     ButtonPressMask | ButtonReleaseMask | OwnerGrabButtonMask |
     EnterWindowMask | LeaveWindowMask | ExposureMask);

3) All other are set as: XSelectInput (the_display, ?which_window?,
    ButtonPressMask | ButtonReleaseMask | OwnerGrabButtonMask |
    EnterWindowMask | LeaveWindowMask | ExposureMask | VisibilityChangeMask);



Does anybody have any suggestions as to why I'm not getting Expose Events??
