Created attachment 1579 [details] plugin load dialogue Tested for new installation and upgrade installation. Not tested on 32bit Fancy HTML viewer plugin is not available after installation. [screen shot of plugin load dialogue attached.] Upgrade install from 3.9 leaves earlier version of fancy.so in place. A "clean" install has no fancy.so in plugins folder.
probably you are missing the dependencies. this is not the right place for this discussion. see here for the right places: http://www.claws-mail.org/MLs.php
Surely a "missing dependency" would raise an error or at least a warning that something or other was missing?
