25.1 Known Bugs
===============
* 'dm' (delete mode) and 'xs' are not handled correctly (they are
ignored). 'xn' is treated as a magic-margin indicator.
* 'screen' has no clue about double-high or double-wide characters.
But this is the only area where 'vttest' is allowed to fail.
* It is not possible to change the environment variable '$TERMCAP'
when reattaching under a different terminal type.
* The support of terminfo based systems is very limited. Adding
extra capabilities to '$TERMCAP' may not have any effects.
* 'screen' does not make use of hardware tabs.
* 'screen' must be installed setuid root on most systems in order to
be able to correctly change the owner of the tty device file for
each window. Special permission may also be required to write the
file '/etc/utmp'.
* Entries in '/etc/utmp' are not removed when 'screen' is killed with
SIGKILL. This will cause some programs (like "w" or "rwho") to
advertise that a user is logged on who really isn't.
* 'screen' may give a strange warning when your tty has no utmp
entry.
* When the modem line was hung up, 'screen' may not automatically
detach (or quit) unless the device driver sends a HANGUP signal.
To detach such a 'screen' session use the -D or -d command line
option.
* If a password is set, the command line options -d and -D still
detach a session without asking.
* Both 'breaktype' and 'defbreaktype' change the break generating
method used by all terminal devices. The first should change a
window specific setting, where the latter should change only the
default for new windows.
* When attaching to a multiuser session, the user's '.screenrc' file
is not sourced. Each users personal settings have to be included
in the '.screenrc' file from which the session is booted, or have
to be changed manually.
* A weird imagination is most useful to gain full advantage of all
the features.
