My Razer Diamondback has in the last few days developed a stiff button! not as kinky as it sounds though 
The left mouse button has become substantially firmer than the right so much so that gaming for a while ends up with a sore finger, anyone experienced this and found a fix?
It was purchased Feb 17 2005, so not long left on the warranty.

I'd get it changed pronto, I doubt you could open it without it being obvious that you had done so.
