[Harp-L] Advice needed

["Leon & Gail Albin" <spock@xxxxxxxxxxx>]

Dear Harp-L friends, 
    I play a Super-64 chromatic, and like it a lot.  Lately the slide button
has been sticking on the release.  This makes playing rather frustrating.
The weather here is humid, I suspect that may be a factor.  I have looked on
the Internet to find a solution to the problem, but so far have not come
across the advice I need.  I am technically challenged and have not tried to
take it apart.  What do you suggest?  Thanks in advance for your help.
Gail
