Jeff,If it's the HTML file then make sure you have the latest templates. wwHelp 4.6 introduced a new way the tree is generated using jQuery so all the scripts have changed. If you're using the stock templates just update the templates.
Otherwise, still update the templates :-). It'll create a backup of the old templates and you'll have to compare to match. I think the only thing that you'll need to replace are wwhelp.js, jquery.min.js and tableofcontents.wcs. Those 3 determine the tree rendering.
Hope this helps,

No. It's not the CHM file. It's the Index2.htm file.
When you click on a node the text disappears and it doesn't expand to the topics below it.
This is in IE9.
I'm pretty sure I'm running the latest HTML HelpBuilder - 4.675.
You are talking about the CHM file, right?
Is this what you're seeing?

I don't think the Project file is damaged or anything. When I preview it it looks great. But when I build the HTML all the nodes are there and then you click on them and then they disappear and there is nothing in the "+".
I'm on a new Win7 64 Bit machine.
I downloaded via your menu item the HTML Workshop. That seems to be there.
Help?
Thanks
