Programming blog

So I just started using Ubuntu, and decided that I needed to set up my Ubuntu installation with all of the cool cross-platform programs I've been using in Windows. I swapped Wamp5 for Lampp, and am using Eclipse successfully instead of Programmer'as Notepad. It's only been a couple of days, but so far I am pretty happy. Apt-get is my new favourite command.

Anyway, I can't for the life of me get Geogebra to work. Below is a screen-shot of what happens when it tries to run. This behaviour makes me suggest that the main applet is running, but that it is unable to find or access the other files it requires.

Java is definitely working fine, I can see Geogebra web applet files, and I can run Eclipse on Java. So far my trouble shooting steps have been to sudo chmod -R 0755 /opt/geogebra and see if it is a permissions issue. I've also tried running Geogebra as root with nother success.

Any other suggestions?
