Does anyone have any suggestions for what is causing the following issue in my library's tutorials?
In Chrome and Safari, clicking on a link in the left-side window sometimes is successful in loading content in the right-side window; sometimes nothing happens. In either situation, clicking on any other left-side link thereafter fails to load the content in the right-side window.
It does not matter whether the link is in a tutorial created several
years ago or today. It does not matter whether the link is on our
domain, it does not matter whether the URL is proxied.
All links work just fine in Firefox.
I am feeling stumped. :/
