Header and Body column misalignment when using sScrollY

Hi,

I am using Datatables 1.9.4 and have linked my page to Datatables debugger link - http://debug.datatables.net/exaquv

There are 3 Datatables in the link, all of them have client side processing and with sScrollY set. When I set the vertical scrolling, the column body misaligns with the header. Please check this issue and advise.

This is my code...
[code]
$('#scheduledJobsTable').dataTable({
"sScrollY": (0.9 * $(window).height()),
"sDom": 'Rrt',
"aaSorting": [[4,'asc']],
"bPaginate": false,
"sAjaxSource": scheduledJobsURL,
"bServerSide": false,
"bAutoWidth" : false,
"bScrollCollapse": true,
"aoColumns":
[
{"mData" : "jobId", "sTitle" : "ID", "sWidth": "2%"},
{"mData" : "jobType", "sTitle" : "Job Type", "sWidth": "10%"},
{"mData" : "jobDetails", "sTitle" : "Parameters", "sWidth": "10%"},
{"mData" : "lastRunTimeString", "sTitle" : "Last Run", "sWidth": "8%"},
{"mData" : "nextRunTimeString", "sTitle" : "Next Run", "sWidth": "8%"},
{"mData" : "singleRunJobTimings", "sTitle" : "Single Run Timings", "sWidth": "15%"},
{"mData" : "recurringRunJobTimings", "sTitle" : "Recurring Frequency", "sWidth": "8%"},
{"mData" : "runStartTimeString", "sTitle" : "Run Start Time", "sWidth": "8%"},
{"mData" : "runEndTimeString", "sTitle" : "Run Stop Time", "sWidth": "8%"},
{"mData" : "activeInd", "sTitle" : "Enabled", "sWidth": "4%"},
{"mData" : "forceRun", "sTitle" : "Force Run", "sWidth": "4%"},
{"mData" : "dayInWeek", "sTitle" : "Scheduled Days", "sWidth": "15%"}
]
});
