Created attachment 69146 [details] Screen capture and example file All catalog records have a MARC preview pop-up that will not close. The pop-up says it's loading, but it never changes. A second pane below the MARC preview will download a file with a name like "bib-17936.dublin-core.xml" if I click export or cancel. I can still work around the pop-up, but it's extremely frustrating.
This sounds like something which frequently happens right after an upgrade, when the browser cache needs to be cleared. Have you tried that?
Such a simple fix! Thanks so so much!
