Script is now updated to confirm whether window was spawned before 
returning false. Limited testing suggests viability - want to throw 
your worst at it?

Can you give me a chapter-and-verse on that? I can't find such a 
prohibition. Even if there exists such a reference, I'll need 
further convincing that, given the full context, its author(s) 
would stand by it. Of course, opening new windows at all ("until 
user agents" yadda yadda) is a violation, so we're probably moot.

I think you are too ready to ascribe godlike qualities to human 
spec/guideline authors.

ps: I didn't see this reply at first; sorry about my subsequent 
suggestion to "read the thread", Jim.
