it's not a constant thing, that's my problem. it's not a specific area, either, which is why i originally thought i was seeing things.
evidently now that i'm hunting for it to appear in the User Guide it won't show
the grey is similar to that in hyperlinks.
when it happens again i'll try to snap a picture but i'm not sure whether it will be crystal with my 2 megapixel phone camera.
as i'm writing this i've been browsing the guide but nothing's amiss. it's as if it knows i'm taking it to the dentist
