Spark top blue menu bar graphic

Hi I am trying to alter the graphic on the spark top menu bar (the blue one with the minimise, maximise and close icon.

I have found the rest of the graphics (in spark.jar file)

does anyone know where this image is kept?

many thanks

Dave

I’ve attached an image showing the graphic i’m after.

This titlebar is a part of the theme (skin) which wasnt created by Jive, so that’s why you can’t find it in spark.jar. This is the Synthetica http://www.javasoft.de/jsf/public/products/synthetica
