ANZ website keeps logging you off?

The ANZ website has a habit of logging me off prematurely, citing security reasons and I just recently figured out why. For some of us, the speed at which websites load can be too unproductive for us that we start clicking buttons for the second time or opening up a link from that website on a new window. Well, that's what causes you to be logged off. If you try to process more than one task at a time on the ANZ website, it will log you off. Hope that helps someone out there.
