I found the answer, use the FN key with prtsc
OMG... My new Toshiba Satellite S70-B(something) wouldn't do anything with the prtsc key. Your solution worked instantly! I don't do fancy stuff with screenshots, but I like to be able to take a shot of a map, paste it onto a Word document, and print it for my husband's quick reference in the car (I'm the one with the NavCommand System... he needs a little paper map.)
Thanks a million!
