If you are on the History screen in Online Banking, and are seeing the transaction descriptions bleeding onto the amounts and overwriting the debits, credits, and balances, then you are likely using Internet Explorer 6, or another older browser version.
While many Online Banking functions work with IE6, it is not considered a supported browser version. Because of its age and lack of security features, many other sites like Google, Facebook, and Amazon have also phased out support for IE6, or are in the proces of doing so.
Internet Explorer 6 was replaced by IE7 in 2006. IE7 was itself replaced by IE8 in 2009, making IE6 two versions old as of this writing. If you are using IE6, please upgrade to the latest version of Internet Explorer, or to the latest version of one of the other supported browsers (Firefox or Safari).
The FAQ on supported browser versions contains links to download the latest versions of the supported browsers.
