In Opera 9 (under Vista64), I put diigolet in the address bar. I don't show the personal bar because I have nothing in it and it's a massive waste of space in my situation. This no longer works in Opera 10 -- at least I think that's the change, since I don't use it very often, but nothing else has changed except for the constant flood of MS updates. If I put diigolet in the personal bar, it works, but in the address bar (right of home, left of the address field) then clicking on it does absolutely nothing. I can even bookmark it and it works -- that is, selecting the bookmark makes the diigolet bar active and visible. The Readability button (http://lab.arc90.com/experiments/readability/) works when placed in the address bar, so it does not appear that adding buttons to the address bar has been disabled.
Very minor related issue: when I go to the diigolet page in Opera, the Notice says the change needed to trusted web sites (I did make this change) is at Opera ==> Tools ==> Preferences ==> Advanced ==> Network ==> Security ==> Trusted web sites. This is not correct; you should remove "Network" from that path.
