Hi folks, Recently, I upgraded one of my Horde systems from 3.3.9 to 5.2.2 on Debian jessie, but it has the problem that lookups of email addresses no longer happen automatically when you begin typing in the "To:" field. This problem does not occur in 5.2.17. Any idea if (and possibly how) this can be fixed in 5.2.2 without upgrading? Thanks, Jaap
