-You almost certainly need to enable the \q{Use background colour to

+You almost certainly need to change the \q{Use background colour to
+erase screen} setting in the Terminal panel. If there is too much
+black space (the commoner situation), you should enable it, while if
+there is too much colour, you should disable it. (See \k{config-erase}.)
+
+In old versions of PuTTY, this was disabled by default, and would not
+take effect until you reset the terminal (see \k{faq-resetterm}).
+Since 0.54, it is enabled by default, and changes take effect
+immediately.
