Seems to me someone had this discussion b4, but I can't find it. After running X1 Producer for a bunch of time, I upgraded to X2. The display of the entire Sonar DAW was perfect for both of them. Everything fit on my hi-rez screen. I just upgraded to X2a, 64 bit Producer and it doesn't want to scruntch down to fit everything on the screen. It looks like I'm running 640x480, but I am really running 1920x1080. I just fired up X1 again and it is correct. I also looked for shortcut keys that would fix it, but..... Sure would be much obliged if someone has and fixit clues.
