Will amend the username when I get a chance. The backslashes were unintentional. It was about the twentieth time I'd tried to find a username not taken, and in my frustration accidentally hit the backslash key when I hit enter.
If I hold the shift key while drawing a rectangle on the screen it looks the slightest bit longer horizontally than vertically. It does however show the same height and width.
Print screen below including both portrait and landscape versions of an A4 page. It is more noticably stretched in the landscape version. Both include the squares using the above method.
Thanks
