I haven't heard about this Gen I feature for a long time but it was a big subject here some years ago. Most folks disliked it and most disabled it--a simple process.
I love being able to adjust my screen, but one position I pretty much never have it in, except on the hottest days, is fully down. I tended to want it wherever I left it at the end of my last ride most all the time. Think about disabling it. If you want to know how, I'm sure somebody here could drag it up from their memory banks.
