Log in page keeps looping

[pythonic13]

I am having trouble getting in to a couple of sites, for example amazon, bank of america, and cooks illustrated on my laptop, what's happening is the log in page will continue to loop but only when I input correct information, if false info is given it shows me the incorrect information page. Any idea why this is happening? I dont think its a browser problem since I used IE, Google Chrome, and Opera to no avail, and on a different computer I can get access to all of these sites.

Thanks for any help

Try adding them as a trusted site.
