Re: 2 Bugs in XEmacs 21.1

Vin> !!2 for the price of 1!! Vin> As I started to investigate a serious problem in XEmacs-21.1, I came Vin> across a less serious bug as well.

(y or n) Hi Vin, I also added jan.vroonhof(a)ntlworld.com to my bbdb today, but had no problems. Here are my versions: (emacs-version) "XEmacs 21.1 (patch 12) \"Channel Islands\" [Lucid] (i386-pc-win32) of Fri Nov 17 2000 on ZJ75T" ; this is actually latest CVS 21.1.12++ (gnus-version) "Gnus v5.8.7" (bbdb-version) "BBDB version 2.00.06 (1999/01/25 06:16:02)" Best regards, Adrian Vin> There is no opportunity to answer either y or n; XEmacs is churning Vin> away, and I can not ^G out either.
