Thank You Mr Gambit,
 Well the problem was that when undocking the controls they created their 
floating window by themselves so I had no way to manage their OnClose event 
at all :(
But I found that I can set the class of the window they use as floating 
window when undocked by the "FloatingDockSiteClass" property.
So now I implemented a descendant of  TCustomDockForm to use with them, that 
does not show the "biSystemMenu" at all :-)
Best Regards,
Stefano B.
