I can't add any meetings in the vCalendar. I've found that files for meetings are being created in the Claws's configuration vcalendar subdirectory. Refreshing of meetings folder in the Claws shows nothing. Software: Claws Mail 3.9.2-55-g74b05b vCalendar 3.9.2git55 Win7 x64
This has been fixed for 3.12.0.
