IR sensor corruption help

[PhilM]

We have a problem with our IR chip. For some reason the fourth button we assigned to the IR chip is messing up. When we turn on our autnomous code using a paperclip in the competition spot in the controler, the fourth button's command starts going on it's own. The remote we have set up was not pointed at the sensor, and nothing was pressed. We quickly removed the paperclip, and things worked again tried it again, same thing happened.
So we tested again by commenting out what button four did on the program. The other three buttons and their reactions worked just fine. We put the missing part of the program back in and BAM! Same problem.

Then someone looked up the update from FIRST, and it said that the IR chip was becoming faulty under circumstances we had been doing. (Leaving the battery plugged in all the time and leaving it hooked up to the robot)

Is the IR chip our problem with the program, and is there any way to fix it?
Or is our problem with our program and the IR chip should be perfectly fine?
Please Help!
