IE7 Onclick Events
IE decides to "remember" visited links (the one you call in the AJAX function), and it simply don't run your onclick event more than perhaps once per click.
I solved this by adding something I'd like to call a no-cache-seed to the url that will be unique for every click, forcing the browser to handle every event as a new URL. Then it works perfectly.
var currentTime = new Date(); var nocacheseed = currentTime.getTime();
