They are unhappy because of flickering icon and wrong pointer ;>.
Favicon in address bar is flickering on hover and mouse cursor does not change to hand pointer (it should because these are linked images).
Started with build 8321 (see the changelog)
UPDATE 15 Jan 2007: Flickering fixed in build 8692. Wrong pointer still here.
UPDATE 8 April 2007: Flickering is back again :(.
