Are you actually constructing a new FXButton each time? If so, you  
need to call create() on the button to realize it, e.g.

	new_button = FXButton.new(p, "Button Label", ...)

Note that a preferable approach (if I understand what you're doing)  
is to just re-use the existing buttons, and change their label text,  

	old_button.text = "New Label for an Old Button"

Hope this helps,
