I'm using Picasa 2.5 Beta (32.43), and I notice from Sysinternals'
TCPVIEW app that it is listening on port 80. So I fire up the browser,
and sure enough, http://localhost returns a blank page. When I close
Picasa, the browser returns "The page cannot be displayed".
What a great idea, a user-mode graphics application listening on the
most attacked port!
Picasa 2.2 (28.20) doesn't do this.
