Every bug report or debug / crash log we receive is looked into, you may not have seen any mention of fixes but for example were currently on Build 280 of the beta image where as the current latest public image is 204, so you can do the maths on that one. dont worry were not ignoring you and every single log you have sent us has been read, i know as every member of the beta team has all of these logs re-directed to our own inboxes when you send them.
