Thank God, I'm not the only one on this planet with that problem.
I'm using the version of "tcsh" that comes with Fedora 8 (manually
installed with "yum" because someone decided that "tcsh" shouldn't
be part of the default installation any longer).

I'm using fvwm2 and xterm, too. ;-)
My .tcshrc contains the usual stuff:
set history=500
set savehist=(500 merge)
Saving and reloading history (by default, ~/.history) worked fine
in Fedora 7 and all previous releases. But in Fedora 8, "xterm -e ...",
"fvwm2" and "tcsh" do not work well together.
If I run "xterm -e ssh localhost" and use fvwm2's window close button,
tcsh's history is lost. It's also lost if I quit my fvwm2 session
(which implicitly closes all windows).
After some research with Google, I lost all hope because nobody
seems to use tcsh, fvwm2 and xterm nowadays. I'm a dying dinosaur.
For the last days on earth, I use the following workaround:
In "~/.logout", I save the history to a backup file:
if ( $?tcsh != 0 ) then
history -S ~/.history_backup
endif
In "~/.login", I load (merge) the history from the backup file
in case the default history file is empty:
if ( $?tcsh != 0 ) then
if ( -z ~/.history ) history -M ~/.history_backup
endif
There seems to be a very rare race condition where even that doesn't
work, but I couldn't reproduce this yet.
Hope that helps ... Andreas
