We have updated our SDK and runtime bits to include improved support for Windows Touch Enabled devices. There were some issues in the Microsoft Surface Input Stack handling of reports sent by a digitizer in serial mode. These issues caused the input stack to not report all touches reported by the digitizer reliably. The new build handles input from serial and parallel/hybrid digitizer more robustly.
We encourage you to use this update, especially if you are building applications that will run on Windows 7 touch enabled PCs. With the Microsoft Surface 2.0 SDK, you can easily create applications to take advantage of the next generation Surface computing device. The applications you create can be adapted for other Windows 7 touch enabled devices as well.
You can find links to the bits at the Microsoft Surface Design and Development Center http://msdn.com/windows/surface
Note that no public APIs were changed in this release. Enjoy!
