Configure Each Browser(Netscape notes) If you’re lucky, Netscape will prompt you • In the “Unknown File Type” box, • click the “Pick App” button, and • browse for/SELECT the Excel executable on your PC If unlucky, (blank screen or Netscape insists on saving): • On Netscape menu bar, • edit/preferences/category/navigator/applications • search each description for “file type details” entry with MIME type = “application/excel” • it may have “description” of “download” (from Norton) • delete it, since it’s not working • regenerate the Excel file and respond to prompt For security reasons, do not uncheck the box: “Always ask before opening this type of file”
