Hi,
This is a problem in v1.14.3, but also exists in 1.10.5 and 1.16.1. Connect to a server, then from the TOOLS menu, select SERVER CONFIGURATION and then "pg_hba.conf". Try to add a new line by double clicking on the last empty line. The dialogue appears that allows you to enter a new entry, but when you save the entry, although the line appears in the pg_hba window, after saving it is not saved and does not reappear when you reopen the pg_hba.conf file.
I've attached a pdf file that has screen grabs and a description of the process which might make it clearer. I hope attachments are allowed, if not, sorry. If the attachment doesn't make it, send me an email off list and I will send it to whomever needs it.
