We use Excel 97 at our office on Windows XP Professional. A couple of users
want to be able to create new files by using new from the right click menu
and selecting Microsoft Excel Worksheet. The creation of the file works fine
in that the filename is filename.xls. When they open the file and add
information and then try to save the file, Excel wants to save as tab
delimited. Creating a file by opening Excel first works just fine. We have
tried this on several computers and the results are the same. For convenience
is there some way to change this behavior?
