Dredge buttons "cancel" and "auto select" does nothing

If you have more than one dredge card in your graveyard, xmage shows a window asking which card you want to dredge before you draw. On this window, the buttons "auto select" and "cancel" does not work.
It's very annoying when you have several dredge cards and you don't want to dredge, you have to click 3 times for each dredge in your graveyard. Would be cool if the button cancel skipped all dredges to let you draw without having to click several buttons.
