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 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 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. 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).
