CSV file extension missing

Hi,
Thanks a lot of for this excellent software!
I am having a little problem - when I attempt to save a CSV the ".csv" file extension is missing.

Here is my initialization function:

function ViewGrid(id) {
				$(id).dataTable({
					"bPaginate" : true,
					"bJQueryUI" : true,
					"bDestroy" : true,
					"bScrollAutoCss" : true,
					"iTabIndex" : -1,
					"sPaginationType" : "full_numbers",
					"sDom" : '<"H"Tfr>t<"F"ip>',
					"oTableTools" : {
						"sSwfPath" : "DataTables/media/swf/copy_csv_xls_pdf.swf",
						"aButtons" : ["copy", "print", {
							"sExtends" : "collection",
							"sButtonText" : "Save",
							"aButtons" : [{
								"sExtends" : "csv",
								"sFilename" : "*.csv",
								"sToolTip": "Save as CSV"
							}, "xls", "pdf"]
						}]
					}
					
				});
			};

I have also tried to do it explicitly, like "something.csv" ; the '.csv' portion is removed from the file name.

Here is my debug info:
