This never used to happen, but often now when I grab the scroll bar on the right in Safari, part of the bar moves with the mouse as it should, but part of it stays at the top (the top of this stay-put bar is rounded, but the bottom is just cut off).
Reason? Bad sign? What to do?
Thanks for your help!
I’ve seen it before - I suspect it’s just a little refresh bug in Safari. It seems to be harmless, if annoying.
