Check the Windows error codes--Win32 error 123 is ERROR_INVALID_NAME ("The
filename, directory name, or volume label syntax is incorrect.").

There are two possibilities that I can think of:

1.  There's a character in the path you're supplying to SelectDirectory
    that is invalid.
2.  It has nothing to do with SelectDirectory.  Error 123 can also be
    caused by setting the current printer to the default when there is no
    default printer, for example.
