personally I found that the mini client is a mass resource hog and is not nearly as good as the normal browser windows. I have a 23 in screen and you can't get anything on that mini client even close, it is so small almost everyone in my guild downloaded it, and then removed it.
hey guys . to who having a problem when click " Login " and it wont appear ( already turn off firewall and antivirus) , install/update ur FlashPlayer for IE(Internet Explorer) . Im pretty sure that will fix it =)
