Improve editing of large fields in the Metadata Editor
When creating and/or editing a MARC field with a large volume of text, such as the 505 or 520 field, occasionally the cursor will appear to be in a different position than it is, so that the user may accidentally delete the wrong characters, or insert them in the wrong place. This appears to happen at random, and saving the record, restarting Alma, and even clearing the browser cache does not consistently fix the problem, even in the short term.

Dear all,
There was an issue in Alma where the color display of subfields in the Metadata Editor distorted the cursor placement indication when editing long fields - this was fixed for May 24 release, so that when the cursor is placed in a field containing more than 1000 characters, the subfield colors are not displayed and the cursor placement indication is accurate.
If you are still seeing issues with cursor placement following May release, please open a Salesforce case. Thanks! -

This phenomenon may even occur when writing within MARC field 245. In this context another issue should be mentionned: that it seems not to be possible to switch from insert mode to overwrite mode when using the Metadata editor.
