The Commonwealth Bank launched its new online banking service on the weekend. Apparently:

“The site also includes a number of security enhancements, but the bank has shied away from launching the site with dual factor authentication.”

If you believe reports in today’s crikey.com.au these security enhancements extended to stopping a large portion of the users from logging in at all. Apparently the login window was blocked by popup blockers in peoples’ web browsers.

Crikey’s bulletin says:

“The problem was anyone who with a pop-up blocker installed was unable to log into the new Netbank on Friday. Why? Because the login button on the new Netbank website was set up in such a way that a pop-up-blocking program was triggered by trying to logon. No matter how many times you clicked on the login button, the login screen was blocked by Internet Explorer’s pop-up blocker.”

“The problem was fixed on Saturday morning with a new version of the login button which is pop-up blocker friendly. Pop-up blockers are installed by default on firefox and new versions of internet explorer. The google toolbar also has a built-in pop-up blocker. You have to wonder where the CBA’s developers have been for the past year because that’s when pop-up blocking programs have become more common.”
