This happens with Copy&Paste: 1) Create a note 2) Collapse it 3) Place the mouse cursor over the inset button. 4) Select the inset with the keyboard 5) type Ctrl-v immediately followed by Ctrl-v. The note inset is then replaced by its own copy. 6) move the inset out of the inset
This is somehow expected from the beginning of using last_inset_. I guess something like boost/signal has to be used (e.g. when an inset is destroyed). Bo
