Since I got this new computer witha Vista OS, I've had one problem after another, thanks to the folks on these boards, I was able to resolve most of these problems, now I went to do my NY Times crossword and got a message to the effect that windows need to know what application to open the puz. extension, same when I tried to upgrade my firmware, this was a bin. extension, I know when I had XP, I went into My Computer, tools, and folder options and was able to assign a program to open them, I don't see this option with Vista. Any ideas? T.I.A.
