Typing cursor disappears after very short time, perhaps 1 second, and has to be restored by mouse click - making typing very slow - it took half a minute to type "perhaps".
This seems to happen quite irregularly, at times I may be able to type several words without any trouble, such as this sentence, and then back comes the dreaded disappearing act.
Also, in Internet Explorer, when I pull down a menu it often disappears before I have time to dig down to the item I want. Could this be connected?
Any suggestions will be most welcome.
