Lightning 1.9 on Thunderbird 17.0 - mostly working if you look in the right place Rated 4 out of 5 stars
Once again after upgrading TB to the latest 17.0 my calendar has vanished. Well, the Calendar and Tasks options are greyed-out from the View menu. HOWEVER...
...Right next to Minimise/Maximise/Close buttons at top right two more little icons have appeared - Calendar and Tasks. These both work fine and all of my events are still there in the calendar (I have no tasks so I can't tell if that works).
I think the fix would be for the developer to re-enable the menu: View: Calendar/Tasks?
Otherwise - great program! Thanks,
