Mobile web window controls click event

Hi,

I am testing on Mobile web in browser / Ti 3.2 / Mac

I added a rightNavButton to a window in a tabgroup, and I added an event listener to alert on click but it didn't alert. Then I tried opening windows with tabs but the back buttons did not function. I even tested the latest Kitchen Sink, the back buttons in all screens do not work.

Is it only for me ?
