My collection works fine with Explorer 6, but I have a problem with Netscape 4: some of my classifiers nodes cannot be opened.

If the node contains too much information the page never loads.

So, if a node contains 10 or 20 elements there's no problem, but when it contains around 30 or more elements, it cannot be viewed with Netscape.

Here's an example of one of those element:
Deadly Public Policy: HIV/AIDS and Government (In)action
Subjects: General Resources ; Blood Safety and Supply ; Injection Drug Use and Drug Policy ; Prisons
Type: Reports and discussion papers
Publisher: Canadian HIV/AIDS Legal Network (Canada, 2004) [Français]

Any idea of the problem/solution?

Thanks,
Jonathan Tremblay
