I am having a problem where the search icon for Ajax Search Pro is appearing over the top of all other elements including a mobile menu. If you view the development site at http://www.lollystick.uk/kayeparmenter with a window width of less than 640 pixels and select the menu icon, you will see the magnifying glass remains visible. I assumed this was caused by a z-index issue but setting and changing z-index values does not appear to fix it.
Any help you can offer would be hugely appreciated.
