Don't confuse New Window with Delayed Popup.
This test imitates a situation when a lot of time passes between clicking and
opening a new window.
In this case the new window can be incorrectly recognized as a Delayed Popup.
There is an intermediate dialogue, which appears after you click the link.
Such situation can arise if
Internet Explorer asks you to save a password etc.
A good popup killer shouldn't block the new windows, which are opened after such intermediate
dialogue.
Click here. The new window should be opened after an intermediate dialogue.
