ernyoka1, the "Window too large" error is not a random error, as far as I can tell. It does happen when Poser crashes after you have used a background image larger than your current resolution, or have opened a .pz3 that was made by someone using a larger resolution than yours. Poser does save settings depending on your monitor resolution. The xml-files are somewhere in Runtime>prefs>ui if I remember correctly. Don't have Poser on this machine, so I can't check. As far as I can tell, it happens only when Poser crashes.

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.
