Opening Excel from browser

[mike]

I have the following code that opens the saved excel file in the browser and
then redirects to previous page. In my browser the file is opened in Excel
and is formatted correctly but on some browsers (All IE) the file is opened
inside of just a plain browser window. Is this an individual browser setting
that is causing this? The formatting comes from opening a template and then
saving to a unique file name.

xlWorksheet.SaveAs(strPath)
Application("PrevFile") = strFile
xlApplication.Quit ' Close the Workbook

strOUT = "<SCRIPT LANGUAGE=javascript>"
strOUT = strOUT & "var newWindow; "
strOUT = strOUT & "newWindow = window.open('" & strFile & "', 'exel', 'HEIGHT=300,WIDTH=400');"
strOUT = strOUT & "newWindow.focus(); window.document.location='AIMInitiatives.asp';"
strOUT = strOUT & "</SCRIPT>"
Response.Write(strOUT)

pay attention to the version of IE and Excel
