oh, i just noticed the note in the online doc which is not present in my 
offline one:
The observer object is attached to the observed object, and is freed 
only when the observed object is freed too.

seems that there is no possibility without destroying the control. is 
there a way to copy an entire object, so i can create a new TextBox with 
the same property values?
