The strangest thing happend to my new 3DS XL. The touch screen left border is partially unresponsive to touch inputs (by the size of about an inch). This happend after I briefly put the charging 3DS above a micro wave oven, which was not on. And yes I'm sure it's that because I was using it before and after the charge. I could not belive it first so I very briefly did the same thing and the unresponsive zone expended a little. i can't find any info on the net as everything I searched linked me to thoses stupid articles of kids trying to charge various devices in there oven... I am not sure if the fact that the 3DS was charging at this moment did that, but never put your 3DS near a micro wave oven, even if it's turned off.
