I have received numerous calls from users lately, stating that they are not able to access the conference sites with IE7. These sites are created from a template, and they are managed on Joomla.

Previously on other sites, there have no problems or complaints. However, with the recent complaints , I suspect that the culprit is my simple jQuery codes since the sites that have been reported have been created recently and incorporated with jQuery features.

Site A (does not contain any jQuery): digitalmediaroi.net

Site B (With recent complaints that fails to load on certain IE7): http://brownfieldscanada.com/

These are the jQuery codes that are running concurrently on a page. Are they using too much memory, therefore causing a problem on IE 7 ?
