I have created a very simple page to reproduce this error
This error is happening on ipad safari or chrome
you can also reproduce it on chrome by emulating Apple Ipad.
Once the page load, Select a radlistboxitem such as "2", now try to press the button. it won't postback.
Any help would be appreciated
