My little boy leaned on my computer keyboard and everything went into a small version. The normal desktop was small and central to the screen with black round the outside of it. I have changed the screen resolution to 1400 by 1050 and that stopped the black edging. However, the icons are still small and up in the top left of the screen and look about a quarter the size they should be. All application I open up, including the internet, are much smaller than normal and the text is very small. E.G. on Google the search is in the middle and the top and about 5/6 of the page is just white. I have attached a jpeg so you can see exactly what I mean.
There is obviously some shortcut on the laptop that has done this and I have checked out the hotkeys but it is none of those. The laptop is an Acer TravelMate 6000. I'm sure that it is something simple but I haven't found out what it is!!
Does anyone have any suggestions please?
