Since getting the last update, 78.4.3 (32-bit) the font and font sizes of my app when I open it are all changed. 1) It does not help to change anything in View. All that does is adjust the PANES and how they appear on my screen. 2) It does not help to change anything in Fonts. All that does is change the font in my replies to others. What I am trying to express, and do not have the techncial langauge to do, is that the "look and feel" and "font" of the appllication/client, is now totally foreign to me. It's small, the font is different, and the entire display when open my TB client is foreign to me. I have been thru every "toggle" and drop down that I know of to adjust this. No dice. All any of the choices in font and encoding only change the font/style of my sending and receiving ....it does nothing at all to change the look/feel of the application when I open it on my desktop. I need my desktop email client t have the look and feel and font size that I am accustomed to for many years or at least the ABILITY to change it to my likiing. If there is some high techie things I need to do in something like Config Editor, then some of us will need a "walk thru". Otherwise, I can't use it anymore, which would make me very sad.
