IE6 Opening New Windows

Hi,

We’re having a problem with a client’s laptop, specifically IE6.

When you type a URL into the address bar and press enter a new instance of IE is opened with that URL, while the original stays at its current page. I’ve gone over every setting I can find to turn this off with no success. This continual opening of new windows is affecting her ability to use our remote access system, as the logon process fails when the browsers are continually reopened.

Does anyone know how I can turn this off?

Cheers,
Sean
