Same problem here!
Windows 7, Chrome 23, HP touchscreen, Sencha touch 2.0.1.
The carousel kitchensink example for Sencha touch 2.1 isn't working either. Can swipe with the mouse, but not with the touchscreen.
I now believe that these issues is caused by a recently introduced chrome feature, 'Force enable touch events'. I found the description of this new feature, introduced Aug '12, here.
The good news is there is a workaround, the 'bad' news is it requires non-stable chrome install.
As I understand, read: from my experimenting, these chrome-interpreted touch events need to be disabled in order for the current windows secha touch to work. Stable chrome only allows you to autodetect ('Force enable touch events' in about:flags disabled) or to enable (that flag enabled). So with an actual touch device you are forced to have these effectively enabled, and sencha touch will not work as expected.
Chrome Canary build 26.0.1407.0 (and hopefully earlier beta/dev streams? confirm pls) have a triple-dropdown for enable/disable/automatic. Setting it to disable... disables it! And voila problem 'solved'.
I hope that support staff has done their homework on this at least for the premium members...
