We have a problem at educationlaw.org. The site is at latest Joomla version. Also, latest version of JCE. Yesterday, the inhouse web person was trying to link to a PDF. When she clicked on the hyperlink tool, up popped an empty white box. The same thing happened for me. I believe the plugin is configured properly. I have the file manager set to Joomla Default. Yet, I have played around with the other options, and they didn't work either. So I don't believe there is anything wrong with the file manager itself. Something is stopping the hyperlink button from pulling the file manager up. We could rever to an older version of the component, but would much rather get the new one working. I am the deverloper of the site. ELA is a client. Thank you.

Thanks for replying, Ryan. I had the same thought as I was trying to debug the problem. Our linksearch settings match your depiction except we don;'t use tags on the site. Something else must be going on.
