Question about Logitech LX7 Cordless Optical Mouse
I have had nothing but good from this LX-7 and it is great. My left mouse button is sticky now and I have to really click harder to get a response. I suspected it was dirty and tried compressed air to an extent. I want to disassemble this baby and check my micro switches and do a thourough cleaning, but I do not see any case screws. Has anyone every dealt with taking one of these apart? I have checked the inside battery compartment and see no screws. My upper buttons are merely flaps in in the casing with no actual button. I did try a fine screw driver and to lift a flap enough for the air cleaning, but it didn't seem to solve my clickability. Any suggestions would be greatly appreciated.
2 screws are located in the battery compartment. They are under that flappy plastic thing that helps you get the Batteries out. The remaining 2 screws are under the "glide pads" in the front of the mouse. Fingernails are helpful ;) Don´t hurt yourself. Try not to get any dirt on the adhesive or you won't be able to stick them back for reassembly.
Anyways.... after opening thats where the Fun really starts... Just spilled some Coffee over mine... still working on how to get all the inner workings out

Buzzinator's diagnostic is right on. The microswitch has a hard plastic (as it should) while the pads on the pillars that reach down and actuate the microswitchs are of a softer plastic. For the left button, the notch is all the way across the pads while for the right button, the notch is still growing from one side, but still works. I don't have epoxy either, nor metal tape (great idea!). So I filled in the notch with superglue! Bad choice, I know, but it's all I have at the moment.

While you're cleaning the insides, you can also make some adjustments that will make your scrolling silent, and allow it to be "free scrolling" so a big flick of the wheel will scroll much further than a little flick.
Remove the scroll wheel's clamp (very front of the circuit board, held on with a single screw). Lift off the entire scroll wheel and the cage it sits in.
Remove the wheel from the cage carefully, then remove the inner portion of the wheel on the left side (the side that doesn't have little radial groove marks). This is the "spring" that is causing tactile and sound feedback for scrolling. Place the "empty" wheel back into the outer cage.
Take the clip you unscrewed from the board (the tiny mouse wheel one) and place it back onto the wheel's cage front. Place the entire combined unit back onto the circuit board, affixing the screw in the clip last. Be sure you didn't lose the tiny spring under the cage that registers wheel down-clicks; it's not affixed with glue, so it can fall. If it did fall, it quickly re-attaches to peg at the back of the cage (not the middle one).

If after cleaning the "Glide pads" with alcohol, the button continues sticky, unscrew just a little the screws under the pads.
