| Created by Emil A Eklund |
| (http://webfx.eae.net/contact.html#emil) |
| For WebFX (http://webfx.eae.net/) |

|-----------------------------------------------------------------------------|
| 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. |
| 2002-08-20 | Added usePersistence flag to allow disable of cookies. |
| 2002-10-23 | (1.14) Fixed a plus icon issue |
| 2002-10-29 | (1.15) Last changes broke more than they fixed. This version |
| | is based on 1.13 and fixes the bugs 1.14 fixed withou breaking |
| | lots of other things. |
