I created a navbar with dropdown and submenu, but the submenu is nearly unuseable with the default browser on android 2.3.5. i included bootstrap 2.2.2 which should have a fix about submenus on mobile devices: http://jsfiddle.net/punknroll/d5KXF/ .When i click on the submenu link the child element appears for a very short time an disappears again. You can't really click on it. Any ideas what is wrong here?

thanx Andy
