Windows 7

[gulliver1]

I have just had a new screen and inverter fitted on my Samsung 510 laptop.
Also had it changed from vista to windows 7.
Now I cant maximise/minimise I used to press Ctrl with - or+ with vista.
but it does'nt work now, also I cant find @ its not where it says it is.
Has anyone else experienced this.

Sounds like your keyboard setting has changed - at least with regards to "@"

Try the " key - does it give you @

Try the £ sign - do you get $

If so, you'll need to change the keyboard setting from US to UK or International.

Once you've sorted the keyboard, try your other problem and see if that has been rectified - it might be something else.
