I experience that drag and drop is quite flaky. Especially annoying is, that when the Project list is filterede by area, I often cannot drag an item to the top of the list, and often not to the 2nd or 3rd place.
I have problems with moving an item to the 1st place in a list. Also, dragging an item way up or down (so that the list has scroll) is difficult. I haven't noticed a problem with moving an item to 2nd or 3rd position.
Thanks for the report on this guys. We have added this to our issues list.
Piggybacking on the topic: moving an event to "Today" list by drag-n-drop often also moves the event within its project, to the place that happens to be beside the "Today" icon. It should be either-or.
