I just had to redo my laptop and choose Ubuntu 12.10 (had 12.04 before). Now I encounter a problem with Lightning, the calendar app for Thunderbird.
My Thunderbird is of version 16.0.2 and I installed Lightning right from the add-ons site inside TB it is of version 1.8 . Anyway I cannot do anything in Lightning. I cannot open the Properties of a calender, it actually won't even properly show the calendar grid at all. Not even the default calendar "Private" works.
Any help is greatly appreciated!
