I have the same problem on WIN 95 with RXFile's FileTree when the
directory is empty. I have to test for the directory empty condition
before invoking Filetree. I also found RXFile linein/lineout methods to
be about 40, yes 40, times slower than the Java readLine/printLn
buffered methods on Win 95. YMMV.
