For example when I alt tab the alt tab 'box' (where all the program icons you have runnong are shown) will stay on my screen until I push the windows button. As well as this when I am typing occasionally nothing will happen then all the text will come up at once.
As well as these to problems somtimes when alt tabbing or simply clicking on the programs on my task bar my cursor will refuse to actually click on anything. I can move it around the screenfine but I cannt alt tab and my cursor refused to actually click on things (i.e. i am trying to close notepad but the red 'x' will not go down and I cannot select programs behind notepad).
Any help would be greatly appreciated, thanks!
