I am using jquery.ui.combify to display combo boxes.

In a test programme the south-pointing arrow is displayed as normal but when integrated into the live programme the arrow is missing even though the functionality works.

I am guessing that I have a missing library or an old library.

Any advice is appreciated.

Thanks
