I have recently been trying to figure out why several sites that we have built including our own have PageRank=0 (white) according to the Google toolbar, when previously they did have PageRank.
<> (Perhaps other people in the world do see a PageRank? I am in Canada and I see a white bar.)
(Perhaps these sites are in the sandbox, but I don't know enough about sandbox to determine this)
In any event, during my investigation, I discovered something strange... if I open the site using href with target=_blank, an actual PageRank DOES appear (4 in our case).
