How did you determin the wind was right down the runway?
From the Tower report several miles away from your aircraft or the wind arrow on the Nav display?
You can have a couple of degrees of crab that won't be terribly noticable visually, but the increased acuity available to you from the PFD/NAV displays would show it.
Furthermore, was athe Diamond over the sword? If so then all was EXACTLY as it should be.
