I use workspaces frequently but suddenly I started getting an alert (101586)
indicating 'This extension cannot be used with the selected file type.
Change the file extension in the file name text box or select a different
file type by changing the Save As type.' I have no extension on my file name
(current) and the Save As type is set to Workspace. I tried adding .XLW to
the file name but that didn't change anything.
