        This is the repair I just emailed back to him.  Works for us-
all depends on how well the surface is prepared for the glue,  I
suppose.  Use 60 grit sandpaper to roughen both mating surfaces and
make sure they are clean and free off greasy finger residue....  it's
not a perfect fix since the buttons slide instead of rolling, but
better cheaper than replacement of the mechanism.  Keep the track
greased with a light oil or some such....
