If you want to copy part of a post you should be able to touch & hold a word & get the Copy/Paste functions, or if you want to copy a link you touch & hold and get the 'Open/Open in New Page/Copy' dialogue.
I can still copy links OK, but with ordinary text in a post, what happens now is that the whole post is highlighted in grey, as if the whole post was a link, but you don't get either type of Copy dialogue, but the bookmark link pops up.
If I turn off bookmarking, I can copy normally, but obviously then I can't bookmark!
i may be wrong, but I think it dates from when the Add message & other links were moved from the poster-name bar, because previously I had to touch one of those, or the poster's name, to get the bookmark link.
So do I now have to choose between being able to bookmark & being able to copy when I'm on my ipad or iphone?
