After so many hours, the window closes where you can no longer edit your posts. This window has probably expired which will no longer permit you to
edit the post.
Give me a sec. and I'll edit something into this post.......
Edit: Adding screen capture.
You can see the "EDIT" button on the top right corner, but it only lasts maybe an hour or two. Perhaps a Mod will know the exact length of the grace
period.
Ok the edit posts button is there, but it is invisible because it is black like the background. Why is that? How come the other two buttons are
white and visible, but the edit posts button is not.
