Hello, everyone.

I've got a page that generates a Spreadsheet object and streams it directly to the browser using CFHEADER and CFCONTENT. The issue is IE8 (surprise! moan). It will open three (sometimes four) instances of Excel 2010, the first of which is blank, and the rest are all the same - the generated content.

I'll include a sample page that I created just for this post. It works great in IE9, IE10, FF21, FF23, and Chrome. Only IE8 (haven't tested 7) opens several Excel apps (all the ones after the first throw an alert box that "such n such file is opened by userx; open read only, or notify when it becomes available?" (I'm paraphrasing.)

Here's my code for test.cfm:
<cfset s = SpreadsheetNew("Metrics","yes")>
<cfset spreadsheetMergeCells(s,1,1,1,3)>
<cfset spreadsheetSetCellValue(s,"TEST Metrics",1,4)>
<cfset brwsrList = "IE7,IE8*,IE8,IE9*,IE9,IE10*,IE10,IE11*,IE11,FireFox,Chrome">
<cfset brwsrIdx = 4>
<cfloop list="#brwsrList#" index="idx">
	<cfset spreadsheetSetCellValue(s,idx,3,brwsrIdx)>
	<cfset brwsrIdx++>
<cfset format1 = StructNew()>
<cfset format1.font = "Calibri">
<cfset format1.fontsize = "11">
<cfset spreadsheetFormatColumns(s,format1,"1-1000")>

<cfheader name="Content-Disposition" value="attachment; filename=test.xlsx">
<cfcontent type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" variable="#spreadsheetReadBinary(s)#" reset="true">
Thank you for your time,
