The message preview in traditional view DOES NOT work/exist. Mouse-over only shows a popup with the subject in it which is pointless since you are mousing-over the clearly visible subject to get a popup of the same text. Also the Preferences->Mail Previews that controls this option does not exist in IMP 5.0.19 Traditional View. In 4.3.4 Preferences->Mail Previews does exist and the feature works. I have tested both 4.3.4 and 5.0.19 on the same server so the environment is exactly the same. Thank you for re checking this. > It's still there, in the traditional view.

Wed, 29 Feb 2012 22:14:28 +0000 https://bugs.horde.org/ticket/11044#t70546 Thanks for the quick and accurate info via email. I modified the ...imp/prefs.php file and all is well now. For those having this issue you need to modify the section as below in ..imp/prefs.php to enable this feature: =========================================================================== // Previews are disabled by default as it can be performance intensive, // especially without caching. $_prefs['preview_enabled'] = array( // Disabled and locked by default 'value' => 0, 'locked' => false, 'type' => 'checkbox', 'desc' => _("Enable message previews?") ); ========================================================================== Did I miss something? I read a lot before testing the migration and never saw anything about this. Also, when enabled, the control of this feature has been moved to Other->Traditional View as opposed to Message Options->Mail Previews. Perhaps the preference entry can be always present but greyed out or otherwise disabled with some note about what must be done to enable it Thu, 01 Mar 2012 06:39:03 +0000 https://bugs.horde.org/ticket/11044#t70554 > Did I miss something?

When jumping a major version, it is the admin's responsibility to scan all config files to be aware of what has changed. We can't possibly describe all the minutiae/changes in every config file. > Also, when enabled, the control of this feature has been moved to > Other->Traditional View as opposed to Message Options->Mail Previews. Sure, because this is exactly the kind of stuff that can be moved around at any time. Preferences are not locked into any specific group. > Perhaps the preference entry can be always present but greyed out or > otherwise disabled with some note about what must be done to enable it No. Please see the comment in the preferences file. Previews in dynamic view are a performance killer (EVERY message on the page has to be parsed, whether it is read or not). It is up to the admin of the server to determine if they want to make this option available to users. Previews will probably go away in traditional view in the near future (most likely for IMP 6). If you want previews you should be using the dynamic view. Thu, 01 Mar 2012 06:50:44 +0000 https://bugs.horde.org/ticket/11044#t70555 Thanks again for the quick responses and accurate answers. Please do not take anything I have said as a complaint as I do appreciate the project and hard work very much. >> Did I miss something?
