I've never heard of this ever. So odd, I had to try it. It didn't happen when I first tried. So just to make sure, I kept hitting the tab key and then it DID happen. I found it would reliably skip to the next item if I hit TAB *three* times. Is this the same for you or does one hit do it? I am also running Windows 7 btw, and did the test on MediaLab 2008.1.33.
