Can anyone tell me how to get a program listed in the "Open With" manager so I can set a default? I've tried several times and it just won't list the programs I want. The first time I tried it (with a pdf), I thought I got it listed and hit enter without checking and now all of the pdf's start Window's Media Center. The Open With manager only list a few programs. I've gone to "find program on the internet" and reinstalling Acrobat Reader & it still won't list it. Anyone?
