hehe, maybe moderately cold for Finland in the winter, but -20 C is cccccold for where I live (west coast of Canada). 'Course, being near the ocean helps moderate the temps a LOT.
By the way, just to screw you up a little, -40 C and -40 F are the same temperature... howzzat for messing with ya?
(and yes, I have been in those temperatures,,, and colder... which has something to do with why I live here now.)
I also have the "special" keyboard. Microsoft Multimedia Keyboard 1.0A. Top right area has the "F Lock" button with a green light. Push to light it up and your probs are gone,,, til next time. (can't seem to get it to stay that way)
I'm not sure if you want to go the trouble of checking, but there is a fairly comprehensive list of background stuff and their recommendations.
Other than that, fiddle with screen res I guess.
