vbCrLf doesnt work in 2007 runtime, but works ok in the main 2007

Hi,

I have a database with a multi line memo field and I am creating carriage
returns using this code:

Me.Text48 = Me.Text48 & vbCrLf & sLst

It works great in Office Access 2007. However when I come to distribute it
among "client" computers running the Access 2007 runtime when executing that
line of code a [?] symbol appears in the text box.

This is what it looks like:

I cant understand why it would work fine in the main Office and not in the
runtime version?

Any ideas would be most grateful!
