I'm having trouble dragging applets out of the browser on Ubuntu 8.10. I'm not a Linux expert, but I followed the instructions from, and I have Java 1.6.0_10-b33 installed and the new plugin activated in Firefox.

However whenever I try and drag an applet out of Firefox, both my applet and this one I get the following exception:

Exception in thread "AWT-EventQueue-2" java.lang.NullPointerException

Does anyone have any suggestions on how to solve the problem?

I installed Update 12 from the early access page and my applets can be dragged out of the browser without that error, so I guess the solution is to grab the latest version of Java 6.
