I noticed this problem when we were testing the upgrade before installing it in the production site. I thought it was a fluke with the PC I tested it on, but now a colleague is reporting the same problem - with a windows 10 OS. Searches seem to proceed normally, until you click through to the biblio record and then it says 'not found'. This problem could not be replicated on a mac. Things we tried that did not make a difference. In Chrome: Clearing browser history / cache, browsing anonymously, and a completely new installation of Firefox (had never been installed on this computer). What appears to have fixed it: Windows update. Our working theory is that the update cleared some cache somewhere on the PC. Has anyone else seen this? And if so, is there a better way to fix it instead of waiting for an update? Elaine Bradtke VWML Our income is severely diminished in these exceptionally uncertain times.
