Yaw wont full function!

[VooDoo]

Hello, I just got Tir3..

And my problem is when I look left in very close point, It stop tracking... When I look right I can do almost 90degree turn
when I look left about 10 degree and it stops tracking..

If I check the tracking window It track fine! I can see very good shape when I look left...

How can I fix that?
Thanks!

Welll.......

About how far away from the camera are you?

Have you tried cleaning the TrackClip (metal clip?)

Have you made any changes to the system recently?

Had it been working?
