About once a week as that remote gnus is painting the subject lines in my spam box, the whole thing freezes solid. screen doesn't respond to escape commands, ~. does nothing, Control-C has no effect, trying to close the window results in the "process not responding" popup. It's not repeatable, in that reconnecting and changing to the same gnus Subject buffer will succeed. I _presume_ some obscure character code is responsible. . . Two questions: 1) Anyone else seen anything like this? 2) Any easy way to provide useful details? I would be happy to run a debugging build if supplied, but really can't run for days under strace. . . ht -- Henry S.
