(googling suggested that there are some bugs in "viewportOffset()") any suggestion?? np tag:railsillustrated.com,2009-01-16:/screencast-endless-page/comments/1237342959 2009-03-18T02:22:39Z Erik said on March 18 2009 **np** - It looks like there might be a few bugs in [Prototypes viewportOffset() function](http://prototype.lighthouseapp.com/projects/8886-prototype/tickets?q=viewportOffset). You might want to try avoiding calling the `viewportOffset()` function and use: $('wrapper').scrollTop directly. You will usually need to check this for every parent element to get the total offset. Also, if you haven't already tried [Firebug lite](http://getfirebug.com/lite.html) you might want to give it a try. It can be useful in debugging this type of problem.
