Revision history for HTML::PopupTreeSelect.

1.4
    - Improved support for sub-classing. (Chris Nandor)

    - Added support for multiple root nodes. (Chris Nandor)  

    - Added new 'parent_var' option to supply parent info in the node
      loop. (Chris Nandor)

    - Added 'inactive' flag to node structure, allowing individual
      nodes to be unavailable for selection.

1.3
    - Added hide_textareas option to workaround bug in Netscape
      6.0 through 7.0 where buttons hovering over textareas are not
      clickable.

    - Now tested on Safari 1.0.

1.2
    - Added ability to drag the widget around the window.

    - Added dropshadow in Windows IE.

    - Added workaround for the select-box show-through problem.

    - Added scrollbars to the widget.

    - NOTE: the default CSS has changed.  If you are using your own
      CSS you'll need to adjust it.  Just run the widget with
      include_css turned on and you'll see the new classes and settings.

1.1
    - Fixed bug where IE sometimes decided to wrap rows.

    - Changed code to setup form_field before calling onselect
      handler.  This allows the onselect handler to submit a form
      with the value already set.
