My Logitech Optical Cordless Desktop Model Number: Y-RK49
How I fixed my mouse?
1. Open the mouse (unscrew the screws)
2. Touch that bump thats the actual clicker of the mouse
3. Try pushing the most "inland" part of the left mouse button frame upward. What happened was that it shifted down ever so slightly.
4. Put it back to together
the last part took me a little while because I couldnt figure out where some of the parts went
the only side effect I got was that my mouse wheel doesnt click. I can spin it and its like an actual wheel... doesnt stop for some times XD. The scrolling works though
well anyway I am glad I fixed my mouse. Hope what I did might help some other person with mouse troubles.

EDIT: it doesnt click when i spin it
