One of the most annoying things about Morgen is that when I drag a task into the calendar and then open it to edit it - it's blocked for a while until it's done 'Updating'. This is the same for adding new events. I often add an event first, then open it to edit it, which is a pain-in-the-ass as I have to wait 30–60 seconds until the 'Updating...' process is complete.
