Hi, John

Maybe some others will answer you from experience. But I think I wouldn't 
use CA glue on it. Too much chance of seizing it completely, and at the 
wrong place.

First, I would look hard at the note, and be sure that what you are 
guessing is what actually happened.

Then, I think I would turn the screw way up, put white glue (Elmer's) on 
the threads down near the rail, and turn it back down to the right place.

If the hole is way too large, I might turn off the button, and turn or pull 
the screw all the way out. Then I might put CA glue into the hole, being 
careful not to completely plug the hole with it. Let it set up for an hour 
or so, and then turn back in the screw.

If none of this works, it is possible to make a new screw hole just to the 
side of the old one. It looks lousy, but usually there is enough clearance 
for it to work. I've tended to do it when the old screw has broken off in 
the hole, and cannot be removed.
