Menu drop down fails in iExplorer 7

Hi!, i'm using this theme and it works fine, but if anyone surf in with iExplorer-7 the main menu fails when you try to select second child in a drop-down menu item.

If you go to: http://www.drupalyag.com/touch/ wich is the demo version, try to select FULL WITH item from LAYOUT item.

Sure is a css thing.

Thanks
