"Black" list pitfalls
There are two interesting nuances when popup blocker software uses
a "black" list.
Please adjust "black" list before testing. Add to "black" list such URLs, which
start with "http://www.webknacks.com/aptest_p" and have the title "Popup".
If you manually enter URL and visit the page, which one is in the "black" list, it should not be closed, as you unambiguously want to visit this page. To test this pop-up killer feature start a new browser and then visit http://www.webknacks.com/aptest_pb2.htm.
Also if you click a link to the page, which one is in the "black" list, it should not be closed, as you unambiguously want to visit this page. To test this popup killer feature click http://www.webknacks.com/aptest_pb2.htm
