Question about asksaveasfilename

[Mike Callahan]

I did find defaultextension, but as you pointed out, it only works with a
single string and does not pay attention to the user's choice in the file
type listbox. I guess I could make my own dialog but I thought that built-in
one would do the trick. Since no one else has responded, I guess it cannot.
