Sorry,we seem to be getting confused here.
Maybe I should clarify it.
I am not referring to the TASKBAR.
I am referring to the Quick Launch section of the taskbar only.
On my computer this is the small group of icons immediately to the right of the START button, which can be single clicked to launch a programme.
There must be a item in the registry which determines it's location.
On some computers it is on the left while others have it on the right.
