Less than a month ago, MSN released a new version of its desktop search toolbar that added tabbed browsing to IE6. The general consensus: it sucked.
Yesterday, they pushed out a new version (02.05.0000.1082) that fixes most of the bugs in the original version, at least based on my very quick and dirty testing. And the desktop search capability still rocks.
I got the download last night; the features related to tabbed browsing still don’t appear in my browser though, even though I have “Turn on tabbed browsing” checked.
