        * GPG asks twice for the new PIN. Thanks to Achim.
        * wptCardDlg.cpp (card_changepin_dlg_proc): Reset the 'safety' pin also.        Only check the passphrase if the backup flag is enabled. Again thanks to        Achim.
 
2005-03-06  Timo Schulz  <twoaday@freakmail.de>
 
        * wptKeySignDlg.cpp (do_fill_seckeylist): Skip secret keys without
        a public key. Noted by Kurt Fitzner.
 
2005-03-22  Timo Schulz  <twoaday@freakmail.de>
 
        * WinPT.cpp (WinMain): --debug as an alias for --enable-debug.
        (enable_mobile_mode): New.
        * wptKeyEditDlg.cpp (keyedit_addsubkey_dlg_proc): Use new
        ID's for adding subkeys.
