hi I am a beginner to computers, so forgive me for a simple problem, I have to print out a sheet for work each week I usually take the option download and then connect the printer and it prints out but suddenly it brings up a box asking where to save it but if I press save it does nothing it let me print out until recently now cant get past that save as option which when I press save does nothing, mnay thanks all I need a computer course obviously,
