>I was looking for Options all the day. Yes, that's a surprising place. :) What's the value for fit to frame? 0? (I don't like to mess it up.)

It depends on your environment. Mine is set to 980, which I find quite ok for reading the messages. I have HD. So, I do not resize all the way through as this would make the reading difficult.

You may try a few ones until you find one that is a good match.
