Thank you Andrew for helping

If you need to add content to the textarea programmatically, readonly won't
stop you, but it does seem to allow the '...scrollTop = ...scrollHeight'
trick to work in IE -- at least it did in IE7 for me.
Only if you need for the user to add content via the keyboard will readonly
cause you difficulties. Even then, one work-around may be to switch readonly
off and on at different times (e.g. set readonly to true briefly when you
add content programmatically and need to auto-scroll to the bottom).
Does this help?
