Forwarded Message Not Visible

Just upgraded to v7 from v6 and copied all my old emails over
I had an email which was forwarded to me in v6 in which I could read the forwarded text.
In v7 the forwarded content is not displayed
It reappears when I try to forward the message myself, so it is there, just not visible
Is this a bug, or is there a setting I have missed in v6

Have solved this myself!
I disabled conversations and the forwarded message reappeared
Not sure why this setting should work like this

Thanks - Disabling the conversations worked
