On incoming TB emails, all fonts/text are too tiny to read. I have to click on reply to bring up another view of the original text email to see the fonts/text in a larger display to be able to read. I did not have this prob. b4 I upgraded to Win10pro from win7, etc. TB is 78.7.1. This is true in all reg. type emails & in the web based newsletters I receive. I have even typed a letter to myself using med. size and letter arrives with the tiny, almost unreadable tiny font.
