The problem that Les is seeing is not due to the scroll bar itself, it 
will probably manifest itself with any light object on a dark background 
at the edge of the screen,  it is the change in contrast / brightness at 
the screen edge that shows the ripple in the power supply, however I may 
be wrong in my diagnosis as I have not seen the monitor in question, 
however this sounds like a standard symptom of a failing power supply.
PS Les, you cannot just "drop in" a new power supply, they are built-in 
to the main circuit board.
