The views shouldn't be Transferable. Only the buffer should be. The views should continue to have the behaviour you had described before, where they recurse to clone their buffer then just clone the view. Since the buffers would already be transferred (the transfering happens before the cloning), it'll all just work. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
