Collectible Card Game Headquarters

Hi all. During hit & run games to Magic, I've seen that something has changed inside the duel. Before, I could move cards with the mouse outside of their staple column (cretures on the left, lands on the right and artifact/enchantments in the center-right part of the screen). After doing so, I could double-click in an empty point of the screen to automatically re-sort all cards in the proper column. So, the last cards with a new position were placed at the end of each column while, now, even after doing so, cards are returned to their first position, following their "coming into play" order.
It is just a minor matter, but is it possible to restore the game as it was before?
Thanks.

On my laptop where I have XP it still works but after I copied it to my PC with windows 7 it sorts them by "coming into play". I don't know if anything changed or maybe it has something to do with OS.

Good hint: I will try as well when my notebook with XP comes back from assistency.
PS: long live to XP, even if 7 is better for multicore CPUs
