Recently, all my new messages and received (text only, no html) messages have
a text box containing the message body.    Sometimes I can right click the
box and remove it, other times I cannot.  On lengthy messages received, if I
cannot remove the text box a large portion of the message cannot be seen and
there is no scroll bar to move it.  How can I disable this irritating text
box?  Thank you for your assitance.
