IE 8 issue

Webpage error details

Message: 'null' is null or not an object
Line: 255
Char: 5
Code: 0
URI: http://handfoto.com/modules/websnapr/js/websnapr.js?e

The error only occurs on the initial load of the site but it stops IE8 in it's tracks until you hit the URL bar a second time.

Can't see anything in the code that is doing it and it isn't an issue in other browsers.
