thanks for the coding example, works perfectly with my browser
(firefox). surely there are pages out there which are abusing such
capabilities for their aggressive advertising campaigns (as usually)
but i think it's not a bad thing on its own.
there are cases where it could be very useful to have
such dynamic popups not opening in a separate browser windows, for
example i'm planning to implement those popups for help functionality on
form fields.
