I'm not sure if I can explain this very well but... When running IE 6-8 on a slow connection, JQuery seems to bomb before the page is ready. Errors like, JQuery is undefined, $ is undefined and so on occur. However, when I switch over to a faster connection (i.e. on the internal network) there are no errors. On a slow connection, the very first line of jquery code in the webpage errors out. I checked the paths to jquery and both the slow and fast connections can find it.
Here is the order of the script tags <SCRIPT src="jquery-1.3.2.min.js" type="text/javascript"></SCRIPT> <link type="text/css" href="jquery-ui-1.7.2.custom.css" rel="stylesheet" /> <SCRIPT src="jquery-ui-1.7.2.custom.min.js" type="text/javascript"></ SCRIPT> <SCRIPT src="jquery.blockUI.js" type="text/javascript"></SCRIPT> <SCRIPT src="jquery.ajaxmanager.js" type="text/javascript"></SCRIPT> <SCRIPT src="jquery.tools.min.js" type="text/javascript"></SCRIPT> <SCRIPT src="jquery.validate.min.js" type="text/javascript"></SCRIPT> Thanks.
