You fixxed the following bug in de Calender:
Now I see. The dragging of the interim event end or start (at the day brake for multi-day events) shouldn't be allowed. It got broken in one of the recent releases. I will fix it.
The Scheduler works a bit differently - usually the event is only visible once (on one line). If you move the event, you will see that the hidden event part is available as well - the full event box moves either way (left or right). The resizing of the visible end is allowed intentionally.
But it looks like this would be a handy feature as well, I'm adding it to the wishlist.
