<DIV><FONT face=Arial size=2>Hi Steve,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>The first thing that comes to mind is =
that maybe
the keys are stuck on front rail guide pin. A rise in humidity could =
cause this
as the felt in the bushings could swell just enough to make the key =
stick.
</FONT><FONT face=Arial size=2>The key should theoretically return =
to its
resting position on its own, even if some centre pin seizes in the
action.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>One other possibility is that your =
client's 5-year
old child has decided to make life difficult for you and dropped a =
couple of
quarters between the keys :-)</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Good luck,</FONT></DIV>
