Show textbox scrollbars without the focus

[Jeremy Hughes]

Basically I want textbox scrollbars to appear even though the textbox doesn't
have the focus. Any ideas?

I have a Msgbox type form with a textbox for messages and a button. If the
message is large the textbox scrollbars show while the textbox has the focus
but I want the button to be the default control (have focus) so the user
can just hit enter to continue. I want the scrollbars to show so the user
can see how to scroll to the rest of the message.

Thanks
Jeremy
