1.5.3 corrects two bugs, one in 1.5.1 and one introduced in 1.5.2 when a fix for the 1.5.1 bug was corrected. Both bugs related to the updating of information in message windows. The first would cause the info in a message display window to not always be redrawn. The second one afflicted only the echo message entry window and resulted in the "From:" field not being displayed.
