Small icon above slider and inactive submenu

Hi, I have two issues with homepage on my web site http://demo.raznirecepti.com/demo/. 1. In Firefox everything is OK with homepage, but in Opera and Chrome small icon appears above slider. 2. On Android tablet and Windows 8 tablet submenu items are inactive - you can not tap on it. With Iphone and Android phone everything is OK. Could you tell me what I am doing wrong? regards, Djapeto
