Security block in Java 7 update 51 (January 2014)

In an attempt to silence the growing number of criticisms about the slow response to fixing security problems in Java, Oracle (the company responsible for Java) has just released an extraordinary update (Java 7 update 51). It is the typical "sledgehammer to crack a nut" approach and has the effect of blocking access to many perfectly safe Java Applets including the Dynamic Family Tree used in this web site. Anyone running this or later versions of Java will now face a complete security block the first time you attempt to view the Family Tree from the link in the main menu (see Fig 1 below). Note that before you can do anything else, you have to close the pop-up notice either by clicking OK or the X at the top right. However, after making the simple change, explained in this downloadable PDF note, the block will be removed (see Fig 2 below) and you may then choose to run the Java Applet for the Dynamic Family Tree.
