This is incredibly useful, greg, and I think I might be able to
make it from here, but could you explain to me a little bit
about how this works?
I see myNewWindow is the window name, and yet you're checking
for the existence of newWindow. Why is this? Is this a generic
search for a new window, or am I unaware of "my" and "new"
prefixes within javascript?
Thanks for your email
