[K12OSN] remove close-option in Icewm window

[Peter Hartmann]

 I'm having a problem with the way users are leaving remote desktop to
server2K3.  Users are just closing the X window instead of logging out
of their rdesktop session.  The server locks up eventually because of
this.  When one closes the Windows window, the user gets logged out
instead of disconnecting.  Is there a way in Icewm to launch a program
wth out the usual buttons in the top right for close, maximize and
minimize?   If there's a different approach please do share it!

Thanks,
Peter
