HELP...Gyro driving us crazy!!!!

Hey everyone!
My problem has confused everyone on the programming team. The gyro were are using is not working. When nothing is moving everything is fine, but when the robot moves, small ammounts of drift appear. No matter what we do, nothing can stop this mystery drift. When the robot is standing still no drift is seen.
HELPPPP!!!:ahh:

Does the robot drift without the Gyro?
What type of feedback system are you using in unison with the gyro to correct the steering?

Can you tell us if the gyro code based on something else, Kevin’s code, WPILib, easyC?
