My Anywhere Mouse has got mushy mouse button syndrome. That is, the left mouse button feels a little bit soft, and it easily double clicks, let's go when I drag something.

Before I repair it at home, rather than bringing it to the store (I kind of need it, it's the only one I have), I'd like to know exactly what I'm doing. It'd be too bad if I tried to repair it, voided the warranty and didn't succeed.

I'm guessing there are screws to open it under the rubber pads. And I suppose I can take those off without breaking them, and put them back on without bending them.

• How is this mouse held together, and what's the safest way to open it?

• Once I have it open, will I be able to fix the problem? What's causing the mushy mouse button?

Here's what I know so far:

• It might be the switch itself that's broken, in which case I shouldn't open it (I can't get a replacement, voiding the warranty to "have a look" seems pointless)

• If there are screws underneath the rubber pads, they're only on the 'front', the back two thirds of the mouse are all battery cover:

  

  There's nothing I can see under the batteries either.

• In the mouse I had before this one, there were sort of springy things connecting the actual button with the switch soldered to the board. They were just lying inside of a bit of plastic, and I could swap the left and right ones easily. If repairing it is more difficult, transferring the problem to the right mouse button would be a very good start.
