Master/Slave windows do not behave as expected on WindowsXP

I have a window that is the master of several others. When I collapse it, or expand it, I
expect that the slave windows also collapse or expand. This works fin on UNIX systems (X11/Motif)
with HP-UX or Linux. But it doesn't under Windows XP. Here, the first time the collapse is working
for all windows, but expanding the master does not expand the slaves anymore.
Why not ? What is the trick ?

I am sending:
        (aBuilder window)
                application: parentBrowser;
                beSlave.

where parentBrowser is supposed to be the master and the window (aBuilder window) the slave.

Karl
