Curios if anyone is seeing intermittent overall extended (15+sec) delays scrolling through menus? I haven't seen a pattern yet, and this isn't when an upload/download/update is happening (that I'm aware of). This started happening maybe a week ago and occurs at different times throughout the day. I push a button and nothing happens. I get bored waiting, go about my business then look again and it's moved to the next screen. Good thing this hasn't occurred during an actual workout. Sure missing just the rugged, purpose built, simplistic 910XT. Bought this to upgrade "that", not necessarily wanting all the extras (like bugs).
