Standard mouse won't right-click

[Bob]

Hi all,

A friend of mine is having trouble with her standard mouse (PS/2 connection)
on a Windows XP machine. She is using the standard mouse driver since the
mouse is a "no name" bought at Office Depot. The problem she is having is
that the right-hand button doesn't do anything. She's gone into the control
panel and changed its settings, but nothing works. She got a mouse from a
friend and it has the same problem on her machine (although it's fine on her
friend's computer). The person who owned the computer before my friend used
a trackball "mouse", so did something get messed up in the registry? Any
ideas?

We haven't tried reinstalling the operating system yet because that takes a
long time.

Thanks,

Bob
