Problem in Dropdown Menu

Hello,

I did install the theme but how to fix dropdown menu. See on your demo website too. When we click or hover on any menu to open its submenu, it is ok but when we mouse out from that menu, drop down menu must be closed automatically but in this theme, it is not getting close automatically but we have to click outside anywhere to close it. So please suggest how I can fix it ?

Sachin
