For several years I have always used an aspect ratio of 3:2 (landscape) in all my Bryce 5.01 drawings. Today I have attempted to change this to a 4:5 (portrait). I remember that I should set a default.br5 file to the new dimensions (960x1200) but try as I may I cannot get this new default file to stick and each time I start Bryce the old landscape screen appears. Can anyone give me details on the steps required to make this change? Bob
