Changed to use mail_save_part to save the data in another thread.
2001-01-28 Not Zed <NotZed@Ximian.com> * mail-display.c (write_data_to_file): Changed to use mail_save_part to save the data in another thread. (save_data_cb): Hide the fileselector once we have a button press, and are saving stuff. * mail-ops.c (mail_save_part): New function to save a part content asynchronously. svn path=/trunk/; revision=7867
