Calendar repeatedly switches off three different calendars
I am running Thunderbird 38.2.0 on Windows 7. Since the latest update, Lightning/Calendar keeps switching off my calendars. Each time I want to look at the calendars (both on the calendar tab, and on the events and tasks pane), I have to select each calendar individually, right click, and tick the 'switch this calendar on' and untick the 'read only' boxes, then click OK. This makes the calendar function pretty useless ... Any solutions that can be suggested?
