Focusing mistery solved !

So after many many times of sending my 40D and "L" lenses to Canon and getting them back with the same focusing problem I finally decided to go via legal channels and demanded full refund for all my Canon equipment,
For reference all my lenses (17-55/2.8 , 24-70/2.8L 70-200/2.8L IS)
with exception of the kit 28-135 front focused on both 40Ds.

I was contacted by Canon representative very soon and they asked me to send the gear there one last time. I actually was tired of sending it back and forth but still agreed as I did like the camera and lenses ( with exception of the front focus issues ).

And see below what they did this time !!! Why wouldn't they do the same job on my many reqular warranty repair requests ?!

Fianally I can go out and take some SHARP pictures.
And thank you all who were supporting me via this ordeal.
