I'm running chrome. Our workboard has a long column on the left, the Backlog. When I try to drag a card from low down on the list to another column, the page won't scroll up when I drag to the top. I have to use my scroll-wheel to scroll up (while still holding the left mouse-button to hang onto the task card) and run my mouse up to the lowest-down card in the destination column. Let go, and the card ends up there -- but with its priority diminished appropriately. Argh.
This used to work fine; dragging to the top of the screen caused scrolling. I also can't see any way to work around this, since I can't find any other method to change the workboard column other than by dragging.
