Help

Hi i have just switched to mac and every time i click enter it makes the page that i am currently on full screen dose anyone know what could be wrong i have tried restoring keyboard shortcuts default and also every time i click space it scrolls to the top of the page can anyone help me.

The only thing I can suggest is

System Preferences > Language & Text > Input Sources

and make sure that the Country selected matches the Keyboard.

If its new take it back to the store and get them to check it as it maybe a hardware problem.
