It is now possible to control whether the +/- buttons (used with multi-level mode to expand/contract levels) are visible. Previously, although the documentation suggested that the xtr'showbuttons0 and xtr'showbuttons fields controlled this, the fields were ignored and the buttons were always made visible.
The interpretation of the two fields has been upgraded to preserve compatibility with existing programs but to now allow the application to hide the top level or lower level buttons, if desired.
