Thanks for your help people. The problem is solved. I have always been a mouse user and used the Right-Click and choose Copy then Right-Click and choose Paste method and that doesn't appear to work for some reason. I suddenly wondered and tried the [Control + C] method then e.g. in an email, Rt-Click and paste and BINGO, success!
I am using the legacy client 6.25 with Windows 8. I cannot find reference for what the version is on the Chromebook.
