/* FlashDetect Script v1.2


Script created by Adam Curry and Eric Upchurch - 02/02.
This script will detect the presence of either the plug-in or
the Active X Control for the Flash Player and return a value
equal to the version number. It will also detect browser and
version number for NS4 - NS6, IE4 Macintosh, and IE on a PC.
If elected, this can also call a pop-up window allowing the 
user to install the required version of Flash. It will also, 
then, set a cookie if the user decides not to install flash. 
This decision will be recalled upon every visit to the site. 
Portions of code borrowed from script created by Robert 
Reinhardt for the Flash 5 
Bible, IDG Books.
