Jon, On to some of your other points: On using your own files, see the updated version of this page: http://www.columbia.edu/~em36/xywritemac.html And please download the latest version of the application.You may need to refresh your browser to see the new version of the page. The page tells you where to find the Xy4 folder inside the Xy4vDosMac application. It tells you exactly what you need to do to use your own settings. Please print out the page and underline everything that says that "you absolutely must" do x, y, or z, because those statements are accurate. Things may or may not go wrong even after you follow all the instructions with fanatical precision, but they are guaranteed to go wrong if you do not follow the instructions with fanatical precision. The window colors are controlled by SETTINGS.DFL. The screen font size is controlled by the Window = setting in CONFIG.TXT, which you should (I hope) be able to change by holding down the Option key when launching the application and choosing the option to set window size relative to the screen. Try 60 first, and only go higher if you have room on your screen for a larger size.
