Wow! you know, I have neer seen a flower emerge from a paph. The one paph I have had reflower for me was in another room because I thought it would be a year or so, when I came back from holiday I found a 3 inch stem with bud. I'd love to see one start coming out the way you have there!

Glad it has finally decided to bloom for you, I'm sure it will be a fantastic bloom.
