Internet Problem that deals with my computer!

[mcg]

Ok, this has happened to me before, but on a different computer. Out of the blue, from nowhere, I get online, and I go to a certain website, and all of the sudden, everything is huge. The text is way too big and it takes up too much space. It used to be smaller before, but now all the text is huge. It only happens on certain websites, so I am really confused. Can someone help me with the problem? I know it isn't my internet, so it has to be something with my computer!

Thanks

When you get on those sites you can hold down the control key and turn your wheel on your mouse, if you have one, to make larger or smaller.
