If you do not see the login window but only the current window, please allow pop-ups for the domain you are currently connected to.
Pop-ups are handled not only by the browser but also by the various toolbars, so please check if you have any toolbars installed.
For Internet Explorer, select "Always allow" by clicking "Options on this site" next to the popup blocker message at the bottom of your browser.
For Google Chrome, click on the pop-up blocker icon in the upper right corner, or click the wrench button to select options and choose Advanced preferences> Pop-up> Exceptions. Select ...> Add ... to add your current site.
For Safari, remove the "Pop-up Blocker" by clicking on the gear icon in the upper right corner.
For opera, select Tools> Preferences from the top menu, select Advanced settings> Manage site preferences> Add, and select the site you're currently accessing from the pop-up options. Select "Open all popup windows" to add them.
If you want to use without popups, or if you are using a non-IE, Safari, Firefox, or non-Chrome web browser, "Click here" to go to the login screen.
