WebOffice flex (flash) is deployed with different skins, the standard (blue) skin and three optional skins: gray, brown and green.

WebOffice flex (flash) client - blue (default) project skin
Every WebOffice 10.7 SP1 project can be either started with a skin parameter (e.g. "&skin=gray") or using no "skin" parameter (the project will be displayed in blue-skin as default).

It is also possible to start a project with a specific skin initially. Configure the desired skin in the Customer Information.
Note: If the Project Skin property is configured, the skin parameter for the WebOffice flex (flash) client (e.g. "&skin=green") will have no effect.
