SOGo 1.3.12C, Thunderbird 10, Lightning 1.2.3. Configured on sogo-integrator inserting the following line in chrome/content/general/ custom-preferences.js: force_int_pref("calendar.autorefresh.timeout", 5); But the refresh time in calendars remain 30 minute. Look at about:config and find calendar.registry.<HASH VALUE>.refreshInterval, but don't know hot set int in custom-preferences.js. Can somebody help? THX -- users@sogo.nu https://inverse.ca/sogo/lists
