Every install of Iron I have there is an odd bug. Any direct links in the bookmark bar w/ it set to viewable randomly show the info like if my pointer was hovering over the link. There doesn't seem to be any set method of reproducing this, and my pointer is no where near the links. It most often appears when I'm opening a new tab. The only way I can clear the info "bubble" is by hovering over the link then it disappears.
