Message box does not give any indication of further information
If you create a message by clicking on the Message icon in the upper right part of the screen, and then create a Message either by responding to a Message or just creating a new Message, the Message area will expand to show 26 lines. However, if your Message is longer than 26 lines, there is no indication to show that a portion of your Message is not being displayed on the screen and you cannot scroll through the Message. The up and down arrows must be used to get to other parts of the message. This is poor design. A better design would be to create a scroll bar after reaching the maximum number of display lines so that the user can more easily scroll through the Message and to indicate additional content beyond the 26 displayed lines.
