Problems with the Gyro, non-stop (but yet not a constant) change in the angle.

Hey.

A few days ago we set the new gyro we got in the KOP on our robot and tried it out, wanting to know the angle of our robot in real time.
It worked great, but yesterday we've noticed a very weird problem: we reset the Gyro and disabled the driving motors so the robot did not move an inch. we looked at the values of the gyro and it still showed a change in the angle. (No more than 0.05 per 5 seconds, negative\positive)
This change seemed to affect our algorithm.
We thought maybe the gyro was damaged, so we tried another Gyro only to come up with the same results.

Anyone came up with this problem? how did you fix it?

Thank you.
