|Re your #17. It sounds like all you really know then is that the left right buttons (presumably) were playing up. Corrosion is unlikely inside a mouse unless it has become wet at some time. Much more likely is contact wear or some other defect inside the micro-switches. The contacts were probably not closing sufficiently. |
When you've cured your WD40 trouble, if necessary perhaps you can get a touch of cleaning fluid to run into the switches. You could drop it on using a very small screwdriver. You might be lucky I suppose. Sometimes giving faulty switches a series of firm taps can get them going, at least for a while.
The irony is that if you had used some implement to apply the WD40 so that it ran into the micro-switches it "might" have helped, although cleaning fluid would have been a more suitable option. The mistake was getting it all over the place and not focussing on where the actual trouble was. That approach just added an extra fault.
Always pop back and let us know the outcome - thanks
