The way this code works is an interesting hack. It creates a hidden iframe with links to all the social networking sites it knows about. Then, it forces the iframe to display visited sites in a different color regardless of what the stylesheet says to do. Then, parses the iframe to find the links marked as ‘visited’.

Anyway, due to the way IE parses and executes scripts and iframes, and the way that my blogging software (Textpattern) puts the scripts within the body element, it was causing IE to crash. Nice, eh? I’ve kludged it by putting in a 1/2 second delay before it tries to execute the script, which seems to alleviate the problem.
