Whenever I am typing while on my browser (Dolphin HD) , how do I make the keyboard disappear? Sometimes it does not do it on it's own and i'm having to view things while the keyboard is there. If i hit the "back" button on the bottom of the EVO, it takes me to the previous page and if I hold the "menu" button down it pulls up the browser's menu. What am I doing wrong if anything? Thanks.
