if you erase the label from the sequence table for a particular node the extensive form game is erased from the main screen and some of the buttons freeze. It is possible to re-enter a node name if one of the active buttons (such as player color) is selected, otherwise you cannot type in the label name; if the node name is re-entered, it does not make the game visible again. Note that the game still appears to exist, even though it is not displayed, as the strategic form of the game can still be viewed.
