BB Torch :: Trakpad Is Not Working

I've had my torch for almost 3 months and the first month was fine but after that, the trackpad started to go haywire. Everytime i try to move it, no matter what the sensitivity is, it always moves everywhere. The trackpad goes crazy. Everytime i try to type it scrolls up in the conversation. Sometimes when i type it gives me random special characters. What's wierd is that it only happens when im outside in broad day light. It works fine when im inside a house or building, and when it;s night time.
