Thanks Bob and Jeff, In the meantime, we found that the issue was resolved on Evergreen systems where we had deployed the changes in Evergreen bug 1797923, "Browser client iframe (catalog, etc.) loading page": https://bugs.launchpad.net/evergreen/+bug/1797923
This change should already be present in Evergreen 3.1.7 and up, Evergreen 3.2.1 and up, and Evergreen 3.3. Unfortunately, we are on Evergreen 3.1.6, so this fix is not in place for us. Thanks for all the links, as this will be helpful to those on our team who are not as out of their depth with the technical aspects as I am! ☺ Regards, April [cid:image001.png@01D51C7B.5C3A56E0]April Durrence NC Cardinal Training Specialist NC Dept. of Natural and Cultural Resources 919.814.6794 phone 919.733.8748 fax april.durre...@ncdcr.gov 109 East Jones Street | 4640 Mail Service Center | Raleigh, North Carolina 27699-4640 Facebook<http://www.facebook.com/NorthCarolinaCulture> Twitter<http://www.twitter.com/ncculture> Instagram<http://www.instagram.com/ncculture> YouTube<http://www.youtube.com/ncculture> Website<https://statelibrary.ncdcr.gov/> Email correspondence to and from this address is subject to the North Carolina Public Records Law and may be disclosed to third parties.
