hello

I was just making a simple door for a little room.
And i wanted to parent the door handle with the door,
When I clicked on the Animation Tab I relised that it was totally empty!!!
I checked some of the other Shelfs too and the Dynamics and Render Tab were also empty!
All the others are completly fine...

I have no idea what could have deleted the buttons inside...
Everything is working perfectly, nothing else has happend...

I'm using Maya Unlimited 6.0
And I was wondering if someone could post these files:

shelf_Animation.mel
shelf_Dynamics.mel
shelf_Rendering.mel

(My Documents\maya\6.0\prefs\shelves)

Thanks...
