I have never been able to copy and paste an Email address into the address bar in an Email when i send from Icloud on any device or OS....is this normal or is it down to me being dumb?

just hold on the email or number .. it will then show after 1-2 sec the contect menu where you can select "copy"

I mean pasting it.....sorry.

same way .. activate the text-box or text field .. anywhere .. press and hold for 1-2 sec .. the context-menu will apear and offer to "paste" (after sucessfully copy Somethings)

it's for desk top computer/MBP

then its just like anywhere else on OSX

Thanks mate....unfortunately it doesn't work on Windows Icould

And what about right click on the name (left click in Windows normally does nothing )

I can't test this sorry, as I don't have an iCloud account for mail
