How can I trigger on the creation of *any* window?

Excellent question. :-)

I was only trying it on the "Help" in Quickmacros itself (Just b/c that was a quick/easy way to make a new window) It *doesn't* work on that, but I just tried it on Excel (it worked), FireFox (it worked), Excel "Help" (it worked)...

Excellent! Thank-you!
