Mozilla Lightning 0.9 not working
I'm using SlackWare current (>12.2) which is working real good, XFCE4.6 and Thunderbird 126.96.36.199.
After installing the Add-On, it was not working (I was unable to create new events or new tasks, these menu points are greyed out). After reading the system requirements, I found out that libstdc++5 is needed, which I installed under /usr/lib.
I uninstalled lightning, made a reboot and a new install of lightning, but it is still not working.
I searched around for some hints, but couldn't find any usefull.
