Cetin,

Just one note of clarification here. Going back to Win98 at least, the Open With... option has always been available. Back on that platform, however, a listing of potential alternative programs was not available as it is in Win2K. I know what you meant here, but just wanted to make sure that others didn't misunderstand.< s >
