NOTE: web pages such as fact sheets attached to items in Lucid v 3.4 interactive key matrices may be considered pop-ups by certain browsers (such as Internet Explorer [IE]) when clicked on by users. If your browser blocks these pop-ups, in your browser's Internet settings you should allow pop-ups for this Lucid tool. Additionally, Internet Explorer may block "active content" on web pages or interactive keys. To allow active content: in Internet Explorer under Tools, Internet Options, Advanced tab, Security category, the box next to the setting "Allow active content to run in files on My Computer" should be checked. Additionally, certain settings under Tools, Internet Options, Security, Custom level, ActiveX controls and plug-ins, may need to be changed.
The Lucid3 interactive key will run embedded within a web browser as a Java applet Player. Java Runtime Environment (JRE) version 1.4.2 (1.5 or greater recommended) must be installed on your computer for the Lucid3 Applet Player to run successfully.
If in the box above you see text that says your Java status is version
1.4.2 (or greater) from Sun Microsystems Inc., and your computer meets
the Lucid3 system requirements, you may open a key:
If you don't see the necessary text in the box above, if the version number displayed is less than 1.4.2, or you receive an error message stating "Java is an unknown command", you can download and install (make sure to uninstall old versions) the latest Java Runtime Environment version from the Java web site at
Note: Some Java versions greater than 1.4.2 may have bugs that affect operation of the interactive key. Bugs can usually be resolved by downloading the latest Java Runtime Environment version from the Java web site. Also, be aware that the JRE is continually being updated for compatibility with operating system updates. It's generally a good idea to have the latest JRE version installed.
You can verify your Java installation status by doing the following:
Windows
Type "java -version" at a Command Prompt window. You can get to the Command Prompt window by either going to Run from the Start button and typing "cmd" or by selecting the Command Prompt menu option from Accessories.
Mac OSX, Linux, Unix and other platforms
Type "java -version" at a terminal window.
OSX comes pre-installed with the JRE and is accessible using Safari. Ensure you have the latest version of JRE by running the software update utility. Internet Explorer version 5.2.3, which is the last version of IE for the Mac, does not support JRE, nor does Opera. Mozilla.org, however, has opted (at least since February 2007) to include the Java Embedding Plugin by default in all of its products (Firefox, Mozilla, or Camino browsers). This will enable them to access JRE and run the key. However, if you require the Java Embedding Plugin, see the links below for information regarding installation, compatibility and updates for the plugin. The Java Embedding Plugin does not work with Explorer or Opera.
Information and Installation instructions for the Java Embedding Plugin for Mac OSX can be found at:
http://javaplugin.sourceforge.net/
To download the plugin directly, go to the Java Embedding Plugin Summary at:

If Java version 1.4.2 or greater is now installed on your computer,
you may open a key:
Lucid3 (Lucid version 3) is software for creating and using interactive
identification keys. Lucid is developed by the Centre
