My cat has just jumped on the keyboard & everything has gone sideways, how do i get it back to normal before i end up with a permanent lean to the left ......LOL 

i had this prob, i clicked my mouse on the bottom(now this is prob the side on yours now!)of the screen where you would normally see some icons,i cant remember if it was a right click or left click,but it opens up some options and you should find it there,its hard to do though with your head on one side hehe, i will have a go in a mo and report back a bit clearer

right, try again, firstly i have windows 7 so it may be diff on yours. on your home screen(the screen which shows when you first start computer up but before you start Internet connection) just click the right hand side of your mouse in the middle of the screen, you  will get some options, go and click on appearance and themes and on there there is a bit where you can change the screen from landscape portrait etc or flip it, you should be able to do it there, i am terrible on computers and i expect someone else who knows a bit would be able to explain it alot easier, good luck

We managed to sort it eventually, thanks!
