I upgraded from Fiesty to Gutsy usIng the online upgrade facility 2 or 3 months ago. I receive messages *like* this regularly: "The Camtasia Studio video content presented here requires JavaScript to be enabled and the latest version of the Macromedia Flash Player. If you are you using a browser with JavaScript disabled please enable it now. Otherwise, please update your version of the free Flash Player by <a href="http://www.macromedia.com/go/getflashplayer">downloading here</a>." I am not sure how to check whether Java or javascript are installed on my Gutsy install. 1. 'Add/Remove Applications' shows the following are installed: 1.1 Sun Java 6 Web Start Sun Java(TM) Runtime Environment (JRE) 6 (architecture dependent files) 1.2 Sun Java 5.0 Runtime Sun Java(TM) Runtime Environment (JRE) 5.0 (architecture dependent files) 2. 'Add/Remove Applications' shows the following are NOT installed: 2.1 Sun Java 6 Console Sun Java(TM) Development Kit (JDK) 6 2.2 Java Web Start 1.4 Blackdown Java(TM) 2 Runtime Environment, Standard Edition 2.3 Sun Java 5.0 Console Sun Java(TM) Development Kit (JDK) 5.0 2.4 Java 1.4 plugin for mozilla/firefox Java plugin for firefox I can't find any reference to javascript in 'Add/Remove Applications'. My Firefox V 2.0.012 browser has 'Javascript enabled' and 'java enabled' in its preferences. Could anybody advise me please?? (I am fairly new to the Linux world) Brian
