//v4.2 - changed the way stored script is called. instead of evaling everything,

//ALSO! this version is using 'display' styles instead of 'visibility' styles.

//v4.0 - now just call "extensionsInitialize(...)". 
//it now checks to see if extensions already have been initialized, and does only creates it if not
