Following the first tutorial, with several miss-fires initially (see separate post) all seemed to be ok until I dropped in the 'root' JDialog as per instructions. Every time Eclipse hangs. Tried both ways of adding it - it doesn't appear to display properly in the GUI and when I click on it in the outline panel eclipse hangs. Sometimes it hangs even earlier.
I've already upped Xms to 512 and made sure Eclipse is using java 1.6 so shouldn't be a performance issue. I'm using a Mac btw.
