I was trying for the whole thread of the conversation, but it only sent one message in that conversation.
I had just seen part of it before and just realised that instead of wrapping it into the width of the screen it had sent the complete part and kept it on one line and I hadn't seen that I had to scroll a long way to the right to see it.
This is very interesting for those interested in the technology end of things.
I get the ame thing as you when I make my Apple Mail window smaller - there is no word wrap and the text at the right just disappears and reappears as you make the window narrower and wider. I ended up with three lines in my forwarded text because the sender of the original text hit the return key.
What I found even more interesting is if you forward that email and reduce width of the Mail window, the text does wrap, but letter by letter, not word by word.
So it seems the text message is forwarded letter by letter (or symbol by symbol).
As to forwarding the whole conversation at once, I think you need an app for that.
o matter where I positioned the thread and selected it just selects a part at seemingly random and sends that.
I have just tried it on another part of the thread and it sent the next part down, not the part I had elected.
On android 4.4.2 the message forwarded is always exactly the one I select.
After I select it and after I select "forward" the message shows up in a separate window so I see exactly what will be forwarded - I can then add or delete or modify that message.
