I am unable to get Touch to work in the simple example that I have attached to this bug report.
I am running Windows 8, but the behavior appears to occur on Windows 7 as well, in the case of Windows 7, the version was the current latest release: R103.
My graphics card passes the test, and the touch does not work in:
The Windows 8 simulator, using Visual Studio 2012 RTM and Windows 8 Release Candidate (the latest commercial version)
FireFox version 13.0.1.
