I type End to send the message and get an error break because the host
(e.g. AI) is down. I C-Z out of the error handler, get back to the Mail
buffer and Abort out of it (planning to Continue later). When I return
to the toplevel of Zmail and try to do anything with the keyboard or use
the mouse to Continue the Who-line says "LOCK". If I M-C-Abort out of
this state, I get the error handler again telling me I am trying to
unlock a process that I didn't lock. I use Peek to look at the
situation and it seems it is the Zmail-Background-process which is
locked. It looks to me like there is perhaps a missing unwind-protect
somewhere to clear a lock. This state is very hard to get out of.
All I can do is warm-boot, which still leaves Zmail sort of confused.
I suspect that the background process is in the error handler. You probably
got a notification about that. You have to get it out of there before the
two processes can synchronize.
