I have been using my iPad for over three years viewing articles on FR and this has never been a problem for me.
I have no idea what settings might cause this to happen, but I suspect it is the process you are using and not the iPad or OS per se.
Sorry I could not help you.
Everything was fine until I upgraded to version 8.whatever. Some iOS forum links insist it is an apple bug. It doesn’t do it at all on some other forums, and does it most of the time, but not all of the time here. Thanks for everybody’s help. It may be something I have to live with.
