Could you check out linebuzz over at http://rickdog.terapad.com/index.cfm?fa=contentGeneric.cwjqvereoypbgmib&pageId=108438
I originally put it on the bottom of the post and it worked intermittently, then I moved it to the top and now it doesn't work if I try to comment above a certain page position, but will work near the bottom of the post. I get this javascript error, as reported by Firebug:
this.aNodes has no properties
initialize()buzz2.js (line 2524)
initialize(7809)buzz2.js (line 2524)
bind()buzz2.js (line 75)
initialize(7809)buzz2.js (line 2524)
[Break on this error] function LBLog(_1){ if(!$("LB_Logger")){ var _2=document.createElement("DIV"); ...
It looks like the error happens on a mouseup event, function LBLog(_1) at the bottom of the script file. Since this is a big long one-liner, it's hard to see what's happening in Firebug.
