Vista

After upgrading Ubuntu to Karmic Koala I experienced a few problems getting Eclipse to work properly – mostly buttons that clicked but triggered nothing. Thankfully, Chris Chrisostomu had already published a blog post on the matter, including instructions for a potential fix that certainly seems to have sorted it out for me:

My thanks go to Chris for writing it up so clearly.
