We just found a bug last night that caused the card size auto-detect code to choose the wrong size in certain cases. In particular it was choosing the “ludicrous” size cards when the screen was much too small to support them. It seemed to only affect Internet Explorer (definitely version 6 and possibly 7 and 8 too) but it was intermittent so we couldn’t see it at first.

At any rate, the bug is now fixed and so if you were unhappy with how the “automatic” setting was working we invite you to try it again. Please let us know if it now chooses the correct size for your browser window.
