title: ExtJS 4 sub menu require double click to activate on iPad
body: <p>Even though Senscha claims ExtJS isn't supported on mobile devices, it works quite well. The only little annoyance that I have is that a sub menu of a popup menu requires two touches ('clicks') to activate.</p>
  
  <p>It seems the first touch activates the menu, the second touch activates the menu option itself. In a menu with multiple options, clicking any option once results in all options being clickable.</p>
  
  <p>I have a popup menu with checkboxes, these have the same issue. Click one activates (i.e., blue background) the option, click 2 actually clicks the checkbox.</p>
  
  <p>I'm sure there's a way to tell the prototype of the menu to register the first touch as a click, but I've been unable to find it. Any help would be greatly appreciated!</p>
