Did I say “a bit rushed”? This patch fixes a problem with the click-through functionality that occurs with complex hyperlinks. If a hyperlink in content has a list of parameters separated by the ampersand (&) character, all except the first parameter are lost. The files in this patch correct this. Drop them into the /bin directory of your v1.4.3297.0 install.
