Hardware :: Mighty Mouse Won't Click

Someone dropped our Mighty Mouse, and now it won't register clicks. When it hit the floor, it kinda fell apart. We put it back together, but now it won't click. We've tinkered around with it a little bit, and opened it up to see if there was something obviously broken... And everything looks like it should be working fine. At this point, it looks like we need a new Mighty Mouse, but I just wanted to see if anyone had any ideas on how we might be able to fix it. There were some other forum posts about the mouse not clicking right clicking, or scrolling, but I get the idea that it was just a hardware problem, where it just stops responding. Au contraire, it isn't working because it suffered blunt trauma.

*also, for other users whose mouse isn't working who are looking for answers, if your track ball isn't working very well, it might just need cleaning. Try turning it upside down and rubbing the mouse on your pant leg or a piece of paper, with moderate force. This will help dislodge debris inside, and help it scroll more easily, and doesn't harm your mouse. If you're having trouble right clicking, try lifting your index finger off the left side of the mouse. The mouse has a sensitive electrical wiring circuit under the area of where your fingers touch, and your mouse may be confused by fingers on both sides of the mouse. The primary click is the left click, so it'll take priority over the right side. Ah, Apple technology is beautiful.
