urlstatus question

[Andre Garzia]

You know Ron, I code network apps every day and every single day I make the
exact same mistake. I first use that callback, then I get frustrated that it
is sent only on errors or transfer complete and then I remember
liburlsetstatuscallback and then I am happy again.

I must have done this like a dozen times!
