+\cfg{winhelp-topic}{logging.flush}
+
+This option allows you to control how frequently logged data is
+flushed to disc. By default, PuTTY will flush data as soon as it is
+displayed, so that if you view the log file while a session is still
+open, it will be up to date; and if the client system crashes, there's
+a greater chance that the data will be preserved.
+
+However, this can incur a performance penalty. If PuTTY is running
+slowly with logging enabled, you could try unchecking this option. Be
+warned that the log file may not always be up to date as a result
+(although it will of course be flushed when it is closed, for instance
+at the end of a session).

 ignore any control sequences sent by the server which use the
 extended 256-colour mode supported by recent versions of \cw{xterm}.
 
+If you have an application which is supposed to use 256-colour mode
+and it isn't working, you may find you need to tell your server that
+your terminal supports 256 colours. On Unix, you do this by ensuring
+that the setting of \cw{TERM} describes a 256-colour-capable
+terminal. You can check this using a command such as \c{infocmp}:
+
+\c $ infocmp | grep colors
+\c         colors#256, cols#80, it#8, lines#24, pairs#256,
+\e         bbbbbbbbbb

+If you do not see \cq{colors#256} in the output, you may need to
+change your terminal setting. On modern Linux machines, you could
+try \cq{xterm-256color}.
