I know its an in-progress but I tried the 20110422 and noticed a change in how button states are set which you might not know

When changing page from a button in a controlgroup and then clicking back button, the clicked button is set to its down state when returning. I listen for the pagehide event and reset the buttons with a mouseout(). There maybe a better way but this works

Now the clicked button state is set by jQM after the pagehide event so the down state is still showing. On the test site, the menu button down states are not being cleared so they do build up.

Thanks
