\S{faq-outofmem}{Question} After trying to establish an SSH 2
connection, PuTTY says \q{Out of memory} and dies.
You almost certainly need to enable the \q{Use background colour to
erase screen} setting in the Terminal panel. Note that if you do
-this in mid-session, it may not take effect until you reset the
-terminal (see \k{faq-resetterm}).

can't be set on per application or per session basis. To increase
the TCP timeout globally, you need to tinker with the Registry.

\c MSTCP\MaxDataRetries
(it must be of type DWORD in Win95, or String in Win98/ME).

Set the key's value to something like 10. This will cause Windows to
try harder to keep connections alive instead of abandoning them.
the alternate screen, and previous versions of PuTTY did not support
this sequence.
+\S{faq-alternate-localhost}{Question} Since I upgraded Windows XP
+to Service Pack 2, I can't use addresses like \cw{127.0.0.2}.
+
+Some people who ask PuTTY to listen on localhost addresses other
+than \cw{127.0.0.1} to forward services such as SMB and Windows
+Terminal Services have found that doing so no longer works since
+they upgraded to WinXP SP2.
+
+This is apparently an issue with SP2 that is acknowledged by Microsoft
+in MS Knowledge Base article
+\W{http://support.microsoft.com/default.aspx?scid=kb;en-us;884020}{884020}.
+
+For a fix, you'll need to contact Microsoft support, as mentioned in
+the KB article. We've been told that the process is reasonably easy,
+and is free of charge; and that the fix will be included in the next
+Windows XP Service Pack (but probably not before).
+
+(\e{However}, we've been told that SP2 \e{also} fixes the bug that
+means you need to use non-\cw{127.0.0.1} addresses to forward
+Terminal Services in the first place.)
+
+\S{faq-missing-slash}{Question} PSFTP commands seem to be missing a
+directory separator (slash).
+
+Some people have reported the following incorrect behaviour with
+PSFTP:
+
+\c psftp> pwd
+\e iii
+\c Remote directory is /dir1/dir2
+\c psftp> get filename.ext
+\e iiiiiiiiiiiiiiii
+\c /dir1/dir2filename.ext: no such file or directory
+
+This is not a bug in PSFTP. There is a known bug in some versions of
+portable OpenSSH
+(\W{http://bugzilla.mindrot.org/show_bug.cgi?id=697}{bug 697}) that
+causes these symptoms; it appears to have been introduced around
+3.7.x. It manifests only on certain platforms (AIX is what has been
+reported to us).
+
+There is a patch for OpenSSH attached to that bug; it's also fixed in
+recent versions of portable OpenSSH (from around 3.8).
