When trying to update an event, 'Save & Close' asks for wether changing only this event or all events. Anyway, either option doesn't do anything. The window stays open and nothing happens.
Thanks @tboston or the bug report !
I just opened the issue on the bug tracker webtop: https://redmine.sonicle.com/issues/155We await the fix by @gabriele_bulfon or @matteo.albinola
