Run the same Flex application in both the web browser and as an AIR executable. CSS work fine in a web browser from a Flex release build, in a Flex debug project and in a AIR debug project.
When an AIR executable (exe) or air file is run from an AIR export release build the CSS color themes completely stop functioning. e.g. if the color theme of white on black background is changed to black on white backgroud - only a small part of the theme change occurs.
The white and black theme CSS's were compiled to SWf files in a project style sub-directory.
