on pc (with touch screen,IE9),I Have a APP ,Have a richselect view,why not scrool display with hand?how to scrool?thanks!

If you are using latest version of touch some kind of scrolling like behavior must work.
IE9 doesn’t support css transaction so there is no way to organize smooth scrolling, code will fallback to more simple solutions, but it must be possible to drag content anyway.
