My question concerns the script that could be called "browserChecker" in 
Chapter 5 of Beginning JavaScript.  Is the NT option comptaible with 
Windows 2000 Professional (the OS I'm working on)?  The reason I ask is 
because when IE attempts to parse the script, it appears most of the 
problem comes from the OS checker section of the script, and that seems to 
be the only (possible) problem, because I haven't found an error in the 
code.  I know 2K is NT-based, and I thought about creating a separate 2K 
option, but I didn't want to create more problems for myself by confusing 
the parser...

Thanks
