Click on event and hit delete button on the upcoming dialog.
When I login to roundcube, make an appointment then I can remove, edit this one.
When I login again to roundcube, and I want to remove the appointment, then the dialog will not coming up...
If I make a new appointment, then I can edit or remove it directly...
The already maked event can be edited AFTER that I have made the new appointment, before it is been frozen....
Scheduled (time changes) is not working? for example: when I have made an appointment, standard time is 1 hour,
is it not possible to change it to two hours? (when I do this then it gives a database error: connection failed)
