Left mouse button. Microsoft Comfort Optical Mouse 3000

Thanks for nothing muktar... anyone know how to open this thing up? I have the same problem with left click button, wouldn't be here if we wanted top buy a new one, Mukkie old pal!

I had the same problem and tryed to solve using some instructions from youtube videos but these don't applied to confort 3000. Anyway, I've opened the mouse (removing four screws under plastic protections in the mouse's base), remove all external plastic parts to expose the defective button (welded to the board). Then I strongly pressed the little black button with a thin tip. My intention was move the internal metal plate (contact plate) to the limit and, this way, forcing a "metalic memory" to returning to the original and correct position. I had no idea if it would make effect, but It worked. At this moment my left button mouse is working fine. I hope it still working in the next few weeks. I don't know.

There is problem in button I advise you to replace the mouse because it cant be repair and the parts is not available for replace .it is better if you go for new one.
