New Samsung S3 update: message enlarge to view full message

[x90x]

I've recently updated to new Samsung software on my S3 & wish I didn't now. Before the update when getting a message you could click on the message in messages to view the whole message in one, instead of having to scroll up & down the page to read the full message. But now won't do this & when trying to click on the message just says copy! Can anyone help please.
