	Thanks alot to Marek for making this script NN6 compatible
	
	NN6 notice: It's *very* slow when it comes to timers, and it's an understatement!)
	
	Opera notice: Opera can identify itself as any browser, depending on value chosen
	in Preferences / Connections / Browser identification. This script assumes that it
	identifies itself as Opera. I dare not say it's a bold assumption, but it's default
	is MSIE 5. Go figure.
