I am having the same problem. The review pane is readable but the reply window is minute. I followed the above suggestions and there was no change. If i roll over all the email and change the typeface to 110 point, it is readable to me. However, the minute type I see is sent in the size I specified (12 point) and is very readable by the receiving party. It is in the reply window that is screwed up. any suggestions on how to fix?
