NewTech Book Store has launched its website to sell books to its registered users all over the world. The website provides a link to register new users. When a new user clicks the link to register himself/herself, the New User Registration page opens in a separate window. This page is then used to enter and submit the essential user details. After the site was launched, it was observed that the feature worked fine in Windows XP Operating System (OS). However, when the same link is clicked in Mac OS or Linux OS, the page is not displayed as the new window does not get opened.

In the preceding scenario, analyze and provide the requirements that have not been considered by NewTech while developing its website?
