tree state behaves inconsistently

[ra]

I am using COOLjsTreePro. The tree state recognition works inconsistently.
i.e. Sometimes a previous other node gets highlighted even when i have clicked somewhere else.
sometimes it is a previous-to-previous node which gets highlighted.
Using IE. 6 and also tested in Ver. 5.5.

I have a separate class for active node.
Put this in tree1_format.js
//21. support bgcolor changing for selected node
false,
//22. background color for non-selected and selected node
["white","#EEEEEE","nav_section_active"]

Also am calling tree.init just before </body>

[ra]

Also have
//17. if true state will be saved in cookies
true,

I've just tested options ##17, 21, and 22 - and there were no buggy behavior...
