All of a sudden, the back monitor stops working with the live view. If I bring up the menu, it works. If I force the back monitor excluding the EVF, nothing changes (so it's not a hw problem with the eye sensor). If I reset factory settings, everything is fine. At this point I can load my personal settings that I had previously saved. It happened me twice; the last yesterday (obviously when I needed the back monitor for flowers), but this time after restoring my settings it stops working again.
