I opened Internet Explorer 8
when I goto to the page
Dash-->Tools--> Available Tools
right click on the "press This!"
I actually get instructions:
"If your bookmarks toolbar is hidden: copy the code below, open your Bookmarks manager, create new bookmark, type Press This into the name field and paste the code into the URL field."
javascript:var d=document,w=window,e=w.getSelection,k=d.getSelection,x=d.selection,s=(e?e():(k)?k():(x?x.createRange().text:0)),f='http://cafedog.wordpress.com/wp-admin/press-this.php',l=d.location,e=encodeURIComponent,u=f+'?u='+e(l.href)+'&t='+e(d.title)+'&s='+e(s)+'&v=4';a=function(){if(!w.open(u,'t','toolbar=0,resizable=1,scrollbars=1,status=1,width=720,height=570'))l.href=u;};if (/Firefox/.test(navigator.userAgent)) setTimeout(a, 0); else a();void(0)
These are one set of instructions for adding the bookmarklet to IE.
I don't why you you have a snapshot, it may be an IE add-on.
