| 2001-01-10 | Original Version Posted.                                       |
| 2001-03-18 | Added getSelected and get/setBehavior  that can make it behave |
|            | more like windows explorer, check usage for more information.  |
| 2001-09-23 | Version 1.1 - New features included  keyboard  navigation (ie) |
|            | and the ability  to add and  remove nodes dynamically and some |
|            | other small tweaks and fixes.                                  |
| 2002-01-27 | Version 1.11 - Bug fixes and improved mozilla support.         |
| 2002-06-11 | Version 1.12 - Fixed a bug that prevented the indentation line |
|            | from  updating correctly  under some  circumstances.  This bug |
|            | happened when removing the last item in a subtree and items in |
|            | siblings to the remove subtree where not correctly updated.    |
| 2002-06-13 | Fixed a few minor bugs cased by the 1.12 bug-fix.              |
