Issue: You are trying to change the purge options on the LiveCycle AdminUI > Health Monitor > Job Purge Scheduler but you can’t edit the field “Purge completed records after” because when clicking into this field it doesn’t get the focus. There is no cursor blinking and you can’t type into the field.
Solution: Tab into the field using the tabulator key on your keyboard. Note that the tab order is so that you have to place the cursor into the field “Recur every” and then press the tab key four times.
Background: An invisible object seems to be overlaying the field.
Issue occurs since LiveCycle ES3 and is still reproducible with ES3 SP2 and ES4 SP1.
