Bug in Pro Version with CSS on selected node?

[Potential buyer]

Hi there -

I'm evaluating the tree before buying the Professional. Noticed an issue in the Pro samples:

http://javascript.cooldev.com/scripts/cooltreepro/demos/lines

- In Tree 1, select the document "SubSubSubNode1",
- Collapse it's parent folder branch ("SubSubNode 1") using the minus icon,
- Select any node (folder or document) from "SubNode2".

The last selected node ("SubSubSubNode1") is incorrectly written and merged onto other tree nodes. This happens only with Trees 1 and 3. I see the common factor here is that Trees 1 and 3 both use the "CSS class for selected node" option (#22).

I'm running IE6 on both Windows 2000 and Windows XP.
Anybody else seeing this? Any patches?

Thanks,
Patrick

We have older version of the tree onilne - 2.3.0. Most recent one - 2.3.1 - has that issue fixed. Eventually we will update our site.
