My desktop with win XP pro seems to be having a problem. As I click on a desktop icon it doesn't open but what I can see is no entry sign [-] is shown up as I move the cursor on the desktop and sometimes it leaves a square in shape with dot lines on the desktop.
I know I am not dragging an icon and dropping it somewhere else but it behaves like this as if I am dragging the icon and it shows the above no entry sign [-] on the screen as the cursors moves a bit further.
I right click and left click to continue and it works temporarily. Similarly, as I browse a website, the contents are selected by itself without having to select the contents whilst moving a mouse.
Your help is much appreciated. Thank you.
