When you use PSPPire (on openSUSE or Cygwin) and try to save a file with "Save as.." the program doesn't use the file extension from the filter. As I try to save a data file and the filter is *.SAV, if I type "myfile" as its name, I would expect the saved file is "myfile.SAV" but instead it is "myfile". Strange enough, within PSPPire it now knows the filename is "myfile.sav" and if I use save, it is saved as "myfile.sav" leaving me with 2 occurences of the same file.
