Error when Saving a Workspace
 

When I try to save a workspace I get an error message that says "The
extension can not 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 tried these suggestions but it doesn't
work. The only file type available is "workspace". This works fine on my
laptop but will not save on my desktop. Any suggestions?
