I have a problem with the taskbar in that the button with the Lt and Rt arrows on in the notification area has disappeared and does not return. Also some of the icons in the notification area which are put there at startup also come and go each time I boot up. All the boxes are checked to show icons on the Taskbar. I have re-installed Windows but I still have the same problem. I do not know wheather this is a bug or somthing to do with my Computer. Has anyone else had this problem or can anyone fix it. Many thanks.
