Had a great time at Build. Lots of really great info and things to look forward to. I also liked seeing C9 front and center this time.
Another way to get touch to work on a second display (or if you have multiple touch displays) is to use the classic Tablet PC Settings control panel. The Setup button on the Display tab is used to associate pen/touch with the proper display.
RIP XP. We had some good times for sure. :)
