Hi and welcom
you do not mention what your windows version is, what the broadband instalation hiccough and reset required entailed?
how old is the computer and who is the 'technician' dealing with it' ? a family friend or a local tech guy?
my windows 98se mouse controlls allow me to adapt most anything so I wonder if somehow sumunt has got gunged up?
one other point, is the mouse wired or wireless and does it have a mouse ball in it that might need cleaning
