Google tracking not allowing further execution

Hey I am using google tracking to find how many people clicked on button. On clicking a button a jquery confirm dialog pops up. On clicking 'yes' tracking is called and then user is redirected to another page. The problem occurs on some PCs that on clicking 'yes' it does not get redirected to another page. Same page gets loaded again.

buttons: [
    {
        text: "Yes",
        click: function () {
            $(this).dialog('close');
            pageTracker._trackPageview(gtc);
            $('form#paymentForm').submit();
        }
    }
]

When I removed that line, the user got redirected to another page. This does not happen on all the computers. I rearly get the PC on which I can encounter this problem.
