I see this is not the only older fully-answered thread you have essentially re-opened.


If you come here from a search engine, you are going to find many posts close to being closed for inactivity that have already been fully answered. The better way to help here: 


— Forget using a search engine.

—Bookmark this forum site map: Site Map - Apple Community

—Choose topic areas where you feel you can best help. 

—Use the site map’ topic links to go directly to those topics.

—Work the first few pages with the newest posts

— Read through any other responses before adding one.


That gives posters the most current information, and they can recognize your contributions with an upvote. Most posters never come back a month later looking for new responses, so the above steps make better use of your time.

I’ve also noticed “stale” threads somehow percolating-up to the “top” of my own Browse window as-if they are live/active threads.


I was tripped-up by one early this morning which had had zero apparent activity for a couple of weeks. (noticed - and corrected - only after my initial reply)


There might still seem to be some lingering site-issues in this regard.
