Something wrong w/ my Z61t keyboard?

I just received my Z61t a few days ago. I really enjoy the overall feel of the letter keys, numbers key, etc. I have noticed that the lower left keys (Fn, Ctrl, windows) seem to make an additional click/sound when pressing them. The same is somewhat true for the lower right keys (arrow keys). It's a little hard for me to describe, but is noticeable when comparing the sound of say any of the letters (A-Z) and then pressing the Fn key. To me, it sounds like the entire keyboard isn't sitting flush onto whatever base it's supposed to sit. So when you press any of the "loose" keys, instead of it bottoming out like it normally does, it sounds like it bottoms out, then the whole keyboard itself bottoms out again on the frame of the laptop. Looking from the side view, everything looks even and there isn't a noticeable slant or anything. Any thoughts out there? Is this normal? Am I crazy? Thanks!

 

My Z61t has the same noise. My T23 also had the same problem with the right side arrow keys after returning from Solectron. It doesn't bother me too much, but I have to attributed it to quality control issues...
