List Fields contain a possibility to use skins to change the looks of the application. This version of List Fields only have one skin, namely the Aqua skin, looking much like Macintosh operating systems. Future versions might be able to use more skins, which will be downloadable from the List Fields homepage .
If you un-select the Use Aqua-skin, List Fields will behave just like any other Windows application.
Note that you must restart List Fields in order to see the effect of your choice.
